Question

the area of a square is 9 square feet. what is the side length?

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 $A = 9$ square feet. We need to find $s$. Rearranging the formula gives $s=\sqrt{A}$. Substituting $A = 9$ into the formula, we get $s=\sqrt{9}$.

Step3: Calculate the value of $s$

$\sqrt{9}=3$ feet.

Answer:

3 feet
