Question

the area of a square is 49 square feet. what is the measure of one of the sides of the square?

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 $A = 49$ square feet, we need to find $s$ from the equation $49=s^2$. Taking the square root of both sides, $\sqrt{49}=s$. Since the side - length of a square cannot be negative, $s = 7$ feet.

Answer:

7 feet
