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 with an area of 81 m2 has the following dimensions:Side length: 9 mPerimeter: 36 mDiagonal: 12.7 m
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
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.
81 square meters
9 inches
To find the length of a side of a square when the area is known, you need to take the square root of the area. In this case, the area is 81 sq m, so the side length would be the square root of 81, which is 9 meters. Therefore, the side of the square is 9 meters.
The length of each of the sides is then 9 metres.
If it is a square then each side will have a length of 9 inches
