36 - here's how you get this answer:
81/9=9
The area is found by multiplying two sides, so take the square of 81 to get the two equal side measures. In this problem, the number is 9.
A square has four equal sides. Two of the sides are 9. Since all sides are congruent, the other two sides must be 9, too. To get the perimeter of a square, you add up all four sides. 9+9+9+9=36 or you could do 9x4 to get 36 also. Good Luck! :)

A square has a perimeter of 36 m What is its area?
1. Okay, so we know the preimeter (all the sides added up) equal 36. 2. So we take the perimeter and devide by 4, because a square has 4 sides. (9) 3. Now that we have 9, we multiply that by another side (9) and get 81. 4. 81 is the area. ---- 36=Perimeter 36/4=Sides l * h=area 9*9=81 81=area
A square has an area of 400 what is the perimeter?
A square with an area of 400 square units has a perimeter of 80 units.
If the area of a square is 81 square inches what is its perimeter?
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.
