You are given a square. If the area of the square is ◂...▸81 in2, you can find the length of one of the sides byResponse area. You can find the perimeter of the square by Response area.

1 answer

To find the length of one of the sides of the square with an area of 81 in², you need to take the square root of the area.

√81 = 9 in

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

To find the perimeter of the square, you can use the formula P = 4s, where P is the perimeter and s is the length of one side.

P = 4(9) = 36 inches

Therefore, the perimeter of the square is 36 inches.
