Chapter 10 Mensuration NCERT Solutions Class 6 Mathematics

Q.1) Find the perimeter of each of the following figures:

""NCERT-Solution-Class-6-Maths-Mensuration-9

Sol.1) Perimeter is the distance covered along the boundary forming a closed figure when you go round the figure once.
Perimeter is the sum of the sides of the polygon
a) Perimeter = 4 + 2 + 1 + 5 = 12 cm
b) Perimeter = 35 + 23 + 35 + 40 = 133 cm
c) Perimeter = 15 + 15 + 15 + 15 = 60 cm
d) Perimeter = 4 + 4+ 4 + 4 + 4 = 20 cm
e) Perimeter = 1 + 4 + 0.5 + 2.5 + 2.5 + 0.5 + 4 = 15 cm
f) Perimeter = 4 + 1 + 3 + 2 + 3 + 4 + 1 + 3 + 2 + 3 + 4 + 1 + 3 + 2 + 3 + 4 + 1 + 3 + 2 + 3 = 52 cm

Q.2) The lid of a rectangular box of sides 40 cm by 10 cm is sealed all round with tape. What is the length of the tape required?
Sol.2) As the lid of the box is sealed around with a tape, we need to find the perimeter of the rectangular box.
Length of the rectangular box = 40 π‘π‘š
Width of the box = 10 π‘π‘š
Perimeter of a rectangle = 2 (length + width)
So, length of tape required = perimeter of the rectangular box = 2 (40 + 10) = 2(50) = 100cm

Q.3) A table-top measures 2 m 25 cm by 1 m 50 cm. What is the perimeter of the table-top?
Sol.3) Length of the table-top = 2 π‘š 25 π‘π‘š = 2 π‘š + 0.25 π‘š = 2.25 π‘š
Width of the table-top = 1 π‘š 50 π‘π‘š = 1 π‘š + 0.50 π‘š = 1.50 π‘š
We know that, Perimeter = 2(length + width)
= 2(2.25 + 1.50) = 2(3.75) = 7.50π‘š

Q.4) What is the length of the wooden strip required to frame a photograph of length and breadth 32 cm and 21 cm respectively?
Sol.4) A frame is put around the photograph and hence to find the length of the wooden strip to frame we find the perimeter of the photograph.
Length of the photograph = 32 π‘π‘š
Width of the photograph = 21 π‘π‘š
Perimeter = 2(length + width)
= 2(32 + 21) = 2(53) = 106 π‘π‘š

Q.5) A rectangular piece of land measures 0.7 km by 0.5 km. Each side is to be fenced with 4 rows of wires. What is the length of the wire needed?
Sol.5) Length of the rectangular land = 0.7 π‘˜π‘š
Width of the land = 0.5 π‘˜π‘š
The rectangular land is to be fenced all around with wire. Hence, perimeter of the
rectangular land = length of the wire.
Perimeter = 2(length + width)
= 2(0.7 + 0.5) = 2(1.2) = 2.4 π‘˜π‘š
Each side is to be fenced with 4 rows of wires. Therefore, total length of the wire needed is 4 times the perimeter.
Total length of wire needed = 4(2.4) = 9.6 π‘˜π‘š

Q.6) Find the perimeter of each of the following shapes:
(a) A triangle of sides 3 cm, 4 cm and 5 cm.
(b) An equilateral triangle of side 9 cm.
(c) An isosceles triangle with equal sides 8 cm each and third side 6 cm.
Sol.6) a) Perimeter = 3 π‘π‘š + 4 π‘π‘š + 5 π‘π‘š = 12 π‘π‘š
b) An equilateral triangle is a triangle whose sides are equal.
Given, side of an equilateral triangle = 9 π‘π‘š
Perimeter = 9 π‘π‘š + 9 π‘π‘š + 9 π‘π‘š OR 3 Γ— 9 = 27 π‘π‘š
c) An isosceles triangle is a triangle with two equal sides.
Given, equal sides = 8 cm and third side = 6 π‘π‘š
Perimeter = 8 π‘π‘š + 8 π‘π‘š + 6 π‘π‘š OR (2 Γ— 8) + 6 π‘π‘š = 22 π‘π‘š

Q.7) Find the perimeter of a triangle with sides measuring 10 cm, 14 cm and 15 cm.
Sol.7) Perimeter of a triangle = 10 π‘π‘š + 14 π‘π‘š + 15 π‘π‘š
= 39 π‘π‘š

Q.8) Find the perimeter of a regular hexagon with each side measuring 8 m.
Sol.8) A regular hexagon has six sides which are equal.
Given the measure of a side of a hexagon = 8 π‘š
Therefore, Perimeter of the hexagon = 6 Γ— 8 = 48π‘š

Q.9) Find the side of the square whose perimeter is 20 m.
Sol.9) Perimeter of a square = 4 Γ— side of a square
Given Perimeter = 20 π‘š
So, 20 π‘š = 4 Γ— 𝑠𝑖𝑑𝑒
Side of the square = 20/4 = 5π‘š

Q.10) The perimeter of a regular pentagon is 100 cm. How long is its each side?
Sol.10) A regular pentagon has five sides which are equal.
So, perimeter of a regular hexagon = 5 Γ— side.
Given the perimeter of a regular hexagon = 100 π‘π‘š
So, 100 π‘π‘š = 5 Γ— side
Side = 100/5 = 20 π‘π‘š

Q.11) A piece of string is 30 cm long. What will be the length of each side if the string is used to form :
(a) a square? (b) an equilateral triangle? (c) a regular hexagon?
Sol.11) a) The string is used to form a square and hence the length of the string is the perimeter of the shape formed.
So perimeter of the square formed = 30 π‘π‘š = The length of the string.
Perimeter of a square is 4 Γ— side
So, 4 Γ— side = 30 π‘π‘š
Side = 30/4 = 7.5 π‘π‘š
b) The string is used to form an equilateral triangle and hence the length of the string is the perimeter of the shape formed.
So perimeter of the equilateral triangle formed = 30 π‘π‘š Perimeter of an equilateral triangle is 3 Γ— side. [An equilateral triangle has three equal sides]
So, 3 Γ— side = 30 π‘π‘š
Side = 30/3 = 10 π‘π‘š
c) The string is used to form a regular hexagon and hence the length of the string is the perimeter of the shape formed.
So perimeter of the regular hexagon formed = 30 π‘π‘š
Perimeter of a regular hexagon is 6 Γ— side. [A regular hexagon has six equal sides]
So, 6 Γ— side = 30 π‘π‘š
Side = 30/6 = 5π‘π‘š

Q.12) Two sides of a triangle are 12 cm and 14 cm. The perimeter of the triangle is 36 cm.
What is its third side?
Sol.12)
Perimeter of the triangle = 36 π‘π‘š
Sides of the triangle = 12 π‘π‘š and 14 π‘π‘š
We know that the perimeter of a triangle = sum of all the sides.
That is, 36 π‘π‘š = 12 π‘π‘š + 14 π‘π‘š + third side
36 = 26 + third side
Third side = 36 – 26 = 10 π‘π‘š
Hence, the measure of the third side of the triangle is 10 π‘π‘š

Q.13) Find the cost of fencing a square park of side 250 π‘š at the rate of 𝑅𝑠. 20 π‘π‘’π‘Ÿ π‘šπ‘’π‘‘π‘Ÿπ‘’
Sol.13)
Side of the square = 250π‘š
The square park is to be fenced all around and hence we need to find the perimeter of the park, i.e. length of fencing required = perimeter of the square.
Perimeter of a square = 4 Γ— side
= 4 Γ— 250 = 1000 π‘š
So, Length of fencing required = 1000 π‘š
Now, cost of fencing per meter = 𝑅𝑠. 20
So, cost of fencing 1000 π‘š = 1000 Γ— 20 = 𝑅𝑠. 20,000

Q.14) Find the cost of fencing a rectangular park of length 175 π‘š and breadth 125 π‘š at the rate of 𝑅𝑠. 12 π‘π‘’π‘Ÿ π‘šπ‘’π‘‘π‘Ÿπ‘’.
Sol.14)
Length of the rectangular park is 175 π‘š
Width of the rectangular park is 125 π‘š
Perimeter of the park = 2(length + width)
= 2(175 + 125)
= 2(300) = 600 π‘š
Cost of fencing per meter = 𝑅𝑠. 12
Cost of fencing the park is = 600 Γ— 12 = 𝑅𝑠. 7200

Q.15) Sweety runs around a square park of side 75 m. Bulbul runs around a rectangular park with length 60 m and breadth 45 m. Who covers less distance?
Sol.15)
Sweety and Bulbul run around the park and hence the distance covered by them is the perimeter of the park.
Sweety runs around a square park of side = 75π‘š
Perimeter of the park = 4 Γ— side
= 4 Γ— 75 = 300 π‘š
Bulbul runs around a rectangular park of length = 60 π‘š and width 45 π‘š
Perimeter of the rectangular park = 2(length + width) = 2(60 + 45) = 2(105) = 210 π‘š
So, Distance covered by Sweety is 300 π‘š and by Bulbul is 210 π‘š.
Therefore, Bulbul covers lesser distance.

Q.16) What is the perimeter of each of the following figures? What do you infer from the answers?

""NCERT-Solution-Class-6-Maths-Mensuration-8

Sol.16) a) Perimeter = 25 + 25 + 25 + 25 = 4 Γ— 25 = 100 π‘π‘š
b) Perimeter = 20 + 30 + 20 + 30 = 2(20 + 30) = 2(50) = 100 π‘π‘š
c) Perimeter = 10 + 40 + 10 + 40 = 2(10 + 40) = 2(50) = 100 π‘π‘š
d) Perimeter = 30 + 30 + 40 = 100 π‘π‘š
Inference: The perimeters of the shapes are all equal.

Q.17) Avneet buys 9 square paving slabs, each with a side of Β½ m. He lays them in the form of a square.

""NCERT-Solution-Class-6-Maths-Mensuration-7
(a) What is the perimeter of his arrangement (i)?
(b) Shari does not like his arrangement. She gets him to lay them out like a cross.
What is the perimeter of her arrangement [(ii)]?
(c) Which has greater perimeter?
(d) Avneet wonders if there is a way of getting an even greater perimeter. Can you find a way of doing this? (The paving slabs must meet along complete edges i.e. they cannot be broken.)
Sol.17)
a) The side of each square is Β½ m and hence the length of the side of the square formed is 1/2 + 1/2 + 1/2 = 3/2 π‘š
So, Perimeter of the square formed is 4(3/2) = 1/2 π‘π‘š
b) Shari arranges into cross form
So, the Perimeter of this shape = 1/2 + 1 + 1 + 1/2 + 1 + 1 + 1/2 + 1 + 1 + 1/2 + 1 + 1 = 10 π‘š
c) It is apparent that Shari’s arrangement has a greater perimeter.
d) No, it cannot be arranged such that the perimeter of the image is greater than 10 π‘π‘š.'

Sol.12) Length of the tile = 12 π‘π‘š; Breadth of the tile = 5 π‘π‘š
Area of one tile = 12 Γ— 5 = 60 π‘ π‘ž. π‘π‘š
a) Length of the rectangular region = 100 π‘π‘š
Breadth of the rectangular region = 144 π‘π‘š
Area of the rectangular region = 100 Γ— 144 = 14400 π‘ π‘ž. π‘π‘š
∴ number of tiles needed = 14400/60 = 240 𝑑𝑖𝑙𝑒𝑠
b) Length of the rectangular region = 70 π‘π‘š
Breadth of the rectangular region = 36 π‘π‘š
Area of the rectangular region = 70 Γ— 36 = 2520 π‘ π‘ž. π‘π‘š
Therefore, number of tiles needed = 2520/60 = 42 𝑑𝑖𝑙𝑒𝑠
