Question

the area of a square garden is 16 ft². how long is each side of the garden? each side is ft long.

Explanation:

Step1: Recall area formula for 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 side - length

Given $A = 16$ square feet, we have $s^{2}=16$. Taking the square root of both sides, $s=\sqrt{16}$. Since the side - length of a square cannot be negative, $s = 4$ feet.
