Question

question 29 of 30
a square has an area of 49 square inches. how long are its sides?
49 square inches? in.
answer here

Explanation:

Step1: Recall the area formula for a square

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

Step2: Solve for \( s \)

Given \( A = 49\) square inches, we substitute into the formula: \( 49=s^{2} \). Taking the square root of both sides, \( s=\sqrt{49} \). Since the side - length of a square is non - negative, \( s = 7\) inches.

Answer:

7 inches
