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.
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.
