you are given a square. if the area of the square is 81 in^2, you can find the length of one of the sides by?
To find the length of one of the sides of the square, you can use the formula for the area of a square which is side length squared.
So, if the area of the square is 81 in^2, you can find the length of one of the sides by taking the square root of the area:
Side length = √(area) = √(81) = 9 inches
Therefore, the length of one of the sides of the square is 9 inches.
