Question

Find the perimeter of a square whose side has a length of 2.25 m.

• A. 225cm
• B. 9m
• C. 3m
• D. 900cm

Answer 1

Answer: (B), (D)

The correct options are
B

9m

D

900cm

Given, side length of the square = 2.25 m

We know that, 1 m = 100 cm
$\therefore$ 2.25 m = 2.25 x 100 = 225 cm
Perimeter of a square = $4\times sidelength$ [Since all the sides of a square are of equal length.]
$\therefore$ Perimeter of the given square $=4\times 225=900cm$
900 cm = 9 m
