Question 16

What is the perimeter of each of the following figures? What do you infer from the answer?

Please scroll down to see the correct answer and solution guide.

a) Length of the side of the given square = 25 cm

Perimeter of the square = 4 $\times$ side.

= 4 $\times$ 25 = 100 cm .

b) Length of the given rectangle = 40 cm.

Breadth of the given rectangle = 10 cm.

Perimeter of the rectangle = 2 $\times$ (length + breadth).

= 2 $\times$ (40 + 10).

= 2 $\times$ 50.

= 100 cm .

c) Length of the given rectangle = 30 cm.

Breadth of the given rectangle = 20 cm.

Perimeter of the rectangle = 2 $\times$ (length + breadth).

= 2 $\times$ (30 + 20).

= 2 $\times$ 50.

= 100 cm.

d) Perimeter of the triangle = Sum of all sides.

= 30 cm + 30 cm +40 cm.

= 100 cm.

Thus, all the figures have same perimeter.
