well i would say 20
9 * 9 = 81 sq inches.
A square is a four sided polygon with four right angles whose sides are all congruent. This means that the area of a square is equal to the length of one side squared. So a square with an area of 81 sq. in. has a side length of 9 inches. The perimeter is the distance around the outside of a figure. For a square, this is equal to four times the side length. Here 4 * 9 = 36. So, the perimeter of this square is 36 inches.
