Question

what is the side length of the square? 4 in. 8 in. 16 in. 32 in. a = 64 in²

Explanation:

Step1: Recall area formula

The area formula for a square is $A = s^2$, where $A$ is the area and $s$ is the side - length.

Step2: Solve for side - length

Given $A = 64$ in$^2$, we have $s=\sqrt{A}$. Substituting $A = 64$ into the formula, $s=\sqrt{64}=8$ in.

Answer:

8 in.
