Q 16. What is the perimeter of each of the following figures? What do you infer from the answers?
(a) The perimeter of the square
= Sum of all the four sides = 4 side
= 4 25
= 100 cm
(b)The perimeter of the rectangle
= sum of all the sides = 2 [length + breadth )
= 2 (20 + 30)
= 2 50
= 100
(c)The perimeter of the rectangle
= Sum of all the sides = 2 [length + breadth ]
= 2 (40 + 10)
= 2 50
= 100 cm
(d)The perimeter of the triangle
= Sum of all three sides of the triangle
= 30cm + 30cm + 40cm
=100cm
We conclude all the given figures have the same perimeter.
