Question

which equation would you use to find the length of a side of a square with an area of 144 square inches?
a. s + s = 144
b. s² = 144
c. s² = \frac{144}{2}
d. s = \frac{144}{2}

Explanation:

Step1: Recall the area formula for a square

The area formula for a square is \( A = s^{2} \), where \( A \) is the area and \( s \) is the side - length.

Step2: Substitute the given area

Given \( A = 144\) square inches. Substituting into the formula gives \( 144=s^{2}\).

Answer:

B. \( s^{2}=144 \)
