Question

The are of a square is 49m2. What is its side length?

Answer 1

We know that the area of a square is 49 square meters.

The area of a square is defined by

$A=l^2$

Where l is the length of each side.

Replacing the given are, we have

$\begin{gathered} 49=l^2 \\ l=\sqrt[]{49} \\ l=7 \end{gathered}$

Therefore, the side length is 7 meters long.
