Question

A square with the side length s has an area of 324 square centimeters. This equation shows the area of the square. x^{2} =324 What is the side length of the square in centimeters?

Answer 1

The previous person was incorrect because if you check it (the area equals the length times the width), 81 times 81 is not 324, it is 6561. You actually have to find the square root of 324 which is 18. And to check it 18 times 18 is 324.
