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.

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.

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.

The area of a square with sides of length x units is x2 square units. So x2 = 81 which implies that x = 9.

81 square meters

9 inches

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.

Length = Width = 9 units.

If it is a square then each side will have a length of 9 inches

The length of each of the sides is then 9 metres.

A square with a side length of 9 meters has an area of 81 square meters.
