Question

Find the perimeters of the squares whose sides are given below:

(i) 10 cm
(ii) 5 m
(iii) 115.5 cm

Answer 1

Perimeter of a square = 4 $\times$ (Length of one side)

(i) Length of one side = 10 cm
Perimeter = 4 $\times$ 10 = 40 cm

(ii) Length of one side = 5 m
Perimeter = 4 $\times$ 5 = 20 m

(iii) Length of one side = 115.5 cm
Perimeter = 4 $\times$ 115.5 = 462 cm
