Question

1. if the area of a square is 121 square feet, how long is one side of the square?

Explanation:

Step1: Recall the formula for the area of a square

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

Step2: Solve for \(s\)

Given \(A = 121\), we have \(s^{2}=121\). Taking the square root of both sides, \(s=\sqrt{121}\). Since the side - length of a square is non - negative, and \(\sqrt{121}=11\) (because \(11\times11 = 121\)).

Answer:

11 feet
