Question

Find the perimeter of a square whose area is $64c{m}^2$.

• A. 32 cm
• B. 12 cm
• C. 36 cm
• D. 24 cm

Answer 1

The correct option is A 32 cm

Given:
Area of the square $=64c{m}^2$

We know, area of a square = side × side
$\Rightarrow 64=(side{)}^2$
$\therefore$ Side of the square = 8 cm

Perimeter of the square $=4\times side$
$=4\times 8$
$=32cm$

Therefore, perimeter of the square = 32 cm
