Question

what is the side length of the square? a = 64 in.² 4 in. 16 in. 8 in. 32 in.

Explanation:

Step1: Recall area formula for square

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 $s^{2}=64$. Taking the square root of both sides, $s=\sqrt{64}$. Since the side - length of a square cannot be negative, $s = 8$ in.

Answer:

C. 8 in.
