Question

the area of a square is 144 in². what is the length of one side of the square? a. 72 in. b. 48 in. c. 36 in. d. 24 in. e. 12 in.

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 $A = 144$ in$^2$, we have $s^2=144$. Taking the square root of both sides, $s=\sqrt{144}$. Since $12\times12 = 144$, $s = 12$ in.

Answer:

E. 12 in.
