Question

The length of one side of a square if it's perimeter is $36$ cm is

• A. 144 cm
• B. 9 cm
• C. 10 cm

Answer 1

The correct option is B 9 cm

Perimeter of square = $36$ cm
$⟹4\times$ side length = $36$ cm
$⟹$ side length = $36÷4$

$⟹$ side length $=36\times \frac{1}{4}$

$⟹$ side length $=\frac{4\times 9}{4}$

$⟹$ side length $=9$ cm

Therefore, Length of each sides of the square = $9$ cm.
