Question

The area of a square is 225 sq cm. Can you find the length of each side of the square?

• A. 124 cms
• B. 144 cms
• C. 24 cms
• D. 15 cms

Answer 1

The correct option is D

15 cms

Let the length of each side of the square = “s” cms

Area of a square $=\text{side}\times \text{side}$

Forming an equation:

$225=\text{side}\times \text{side}$

$s^2=225$

$\text{s}=\sqrt{225}$

$\text{s}=15\text{cms}$
