Question

ou are given a square. If the area of the square is 81 in2
, you can find the length of one of the sides by

Answer 1

You can find the perimeter of the square by

Answer 2

taking the square root of the area.

Using the formula for the area of a square (Area = side length x side length), we can plug in the given area of 81 in^2:

81 = side length x side length

Now, we can take the square root of both sides to find the length of one of the sides:

√81 = √(side length x side length)
9 = side length

Therefore, the length of one of the sides of the square is 9 inches.

Answer 3

multiplying the length of one side by 4.

Since each side of a square is equal in length, the perimeter is simply 4 times the length of one side.

For the square with a side length of 9 inches:

Perimeter = 4 x side length
Perimeter = 4 x 9
Perimeter = 36 inches

Therefore, the perimeter of the square is 36 inches.
