Question

the area of a square is 49 square feet. what is the measurement of one of the sides of the square? a 5 feet b 6 feet c 7 feet d 8 feet

Explanation:

Step1: Recall the area formula for a square

The area formula of a square is $A = s^{2}$, where $A$ is the area and $s$ is the side - length.

Step2: Solve for the side - length given the area

We know that $A = 49$ square feet. So, $s=\sqrt{A}$. Substituting $A = 49$ into the formula, we get $s=\sqrt{49}$.

Step3: Calculate the square - root

Since $7\times7 = 49$, $\sqrt{49}=7$.

Answer:

C. 7 feet
