A square with a side length of 9 units has an area of 81 square units.
9² = 81 square units.Area= length*length= 9*9= 81 unit square
yeah. a 3cm by 3cm square.
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 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.
The square of 9 is calculated by multiplying 9 by itself, which equals 81. In mathematical terms, this can be written as 9^2 = 81. The square of a number represents the area of a square with sides of that length.
6m * * * * * Actually it is 9 square metres.
The answer is 81m2A square with 9 meter sides has an area of 9*9 = 81 square meters.
9 square cm
A square with a side length of 9 meters has an area of 81 square meters.
A square with a side length of 9 meters has an area of 81 square meters.
81
9² = 81 square units.Area= length*length= 9*9= 81 unit square
Squares don't have 9 sides. Question makes no sense.
9² = 81 square units.Area= length*length= 9*9= 81 unit square
The length of each of the sides is then 9 metres.
A square with a side length of 3 cm has an area of 9 cm2
Area of a Square = Length*Length = 3*3 = 9 square feet.
