All sides of a square are the same. So, only two numbers multiply to 81, 9 times 9. Since there are 4 sides in a square, 9 + 9 + 9 + 9 is 36. 36 is your answer.
Area of square = 81 cm2 so side of square = 9 cm and then perimeter = 4*side = 36 cm.
The area of a square whose perimeter is 36 inches is: 81 square 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.
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 with an area of 400 square units has a perimeter of 80 units.
Perimeter is 36 feet.
The area is 81 square units.
36
81
Its area is 81 square inches.
Area of square = 81 cm2 so side of square = 9 cm and then perimeter = 4*side = 36 cm.
The area of square with a perimeter of 36 is 81. If the perimeter is 36, then each side must be 36 divided by 4, or 9. The area of a square is side squared, so that is 9 squared or 81.
The area of a square whose perimeter is 36 inches is: 81 square inches.
For a square Area = Side2 thus Side = √Area = √81 = 9cmFor a square, Perimeter = 4 x Side = 4 x 9 = 36cm
36 cm
Perimeter of the square: 4*9 = 36 feet
If the area is 81 square feet what is the perimeter?
