Question

the area of a square can be found using the equation ( a = s^{2} ), where ( a ) is the area and ( s ) is the measure of one side of the square. choose the equation for how to solve for the side length of a square to its description. a square has an area of ( 99 mathrm{in}^{2} ) ( s = 99 mathrm{in} ). ( s=(99)^{2} mathrm{in} ). ( s=sqrt{99} mathrm{in} ).

Explanation:

Step1: Start with the area formula

Given \( A = s^{2} \), where \( A = 99\ \text{in}^2 \).

Step2: Solve for \( s \)

To isolate \( s \), take the square - root of both sides. So \( s=\sqrt{A} \). Substituting \( A = 99\ \text{in}^2 \), we get \( s=\sqrt{99}\ \text{in} \).

Answer:

\( s=\sqrt{99}\ \text{in} \) (the third option)
