Question

if i know the area of a square, how do i find the side length? i square the area. i divide the area by 4. i divide the area by 2. i take the square root of the area.

Explanation:

The formula for the area of a square is $A = s^2$, where $A$ is the area and $s$ is the side - length. To find $s$ when $A$ is known, we solve the equation $A = s^2$ for $s$, which gives $s=\sqrt{A}$.

Answer:

I take the square root of the area.
