The length of a square with an area of 81 would be 9.
9² = 81 square units.Area= length*length= 9*9= 81 unit square
A square with a side length of 9 units has an area of 81 square units.
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.
A = s^2 81 in^2 = s^2 √(81 in^2) = √s^2 9 in = s Thus the side of the square is 9 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.
To find the side length of a square with an area of 81 square inches, you take the square root of the area. The square root of 81 is 9. Therefore, the side length of the square is 9 inches.
To find the length of a side of a square when the area is known, you can use the formula: Area = side length². Given that the area is 81 ft², you can take the square root of 81 to find the side length. Thus, the side length is 9 feet.
9² = 81 square units.Area= length*length= 9*9= 81 unit square
9² = 81 square units.Area= length*length= 9*9= 81 unit square

The area of a square with sides of length x units is x2 square units. So x2 = 81 which implies that x = 9.
81
The area of a square is calculated by squaring the length of one of its sides. If the side length is 9 units, the area is (9 \times 9 = 81) square units. Therefore, the area of the square is 81 square units.
Area of square = x2 where x is the length of each side. So x2 = 81 sq ft x = sqrt(81) ft = 9 ft
Since the square root of 81 is 9, each side of the square would be 9 centimetres in length.
