Question

Find the perimeter of a square, each of whose sides measures:
(i) 3.8 cm
(ii) 4.6 cm
(iii) 2 m 5 dm

Answer 1

(i) Side of the square = 3.8 cm
Perimeter of the square = (4×side)
= (4×3.8) = 15.2 cm
(ii) Side of the square = 4.6 cm
Perimeter of the square = (4×side)
= (4×4.6) = 18.4 cm
(iii) Side of the square = 2 m 5 dm
= (20+5) dm (1 m = 10 dm)
= 25 dm
Perimeter of the square = (4×side)
= (4×25) = 100 dm
