Question

The perimeter of a square is 124 cms. What is the length of its side?

• A. 124 cms
• B. 31 cms
• C. 93 cms
• D. 62 cms

Answer 1

The correct option is B

31 cms

Let $p$ be the side of the square.

Perimeter of a square = $4\times \text{side}$

Hence 4p = Perimeter of the given square

Forming an equation:

$4p=124$

$\Rightarrow p=\frac{124}{4}=31\text{cms}$
