Question

question 3. the area of this square is 144 square inches. what is the length of each side, s, of the square? a. 72 inches b. 36 inches c. 16 inches d. 12 inches

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: Substitute given area and solve for $s$

We know $A = 144$ square inches. So, $s^2=144$. Taking the square root of both sides, $s=\sqrt{144}$. Since $s>0$ (as it represents a length), $s = 12$ inches.

Answer:

D. 12 inches
