Question

1. the area of a square was 100 square miles. fin the length of 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.

Step2: Solve for \(s\)

Given \(A = 100\) square miles. Substitute into the formula: \(s^{2}=100\). Then \(s=\sqrt{100}\) (since \(s>0\) for a length).

Answer:

The length of one side of the square is \(10\) miles.
