Area of square = 81 cm2 so side of square = 9 cm and then perimeter = 4*side = 36 cm.

Area is length times width. So... 9x9=81

Length = Width = 9 units.

The sides of the square will each measure 9 units

Length times width will give you area. So this comes out to 81 square feet.

This is one of those areas where there is ambiguity.A 9 cm square is a square whose sides are 9 cm and which therefore has an area of 81 cm2.But 9 cm2 represents an area of 9 square centimetres. The shape of this area is unspecified.When written in the above form, the ambiguity is less obvious but in spoken form it is.

81 inches squared, because a square has all 4 sides equal, and since area is width x height, the area is 9 x 9 = 81

Area= Length x Width Squares have all four sides equal Therefore: Length=Width therefore Area=Length^2 hope that helps

The area of square is : 81.0

Length = 9 Width = 9 Your rectangle is a square.

36, area is equal to length X width, perimeter is equal to 2(length)+2(width) in a square length is equal to width, so we take the square root of the area to find that both are 9, which means the perimeter is 9 X 4, 36.

A cube has six faces. Therefore, its surface area is 6 times a face's area.The area of a square whose edges measure 9 cm is 81 cm2.Therefore, the surface area of a cube whose edges measure 9 cm is 6*81 = 486 cm2.

To get the area you multiply the length and the width. Doing the math gives an answer of 81 square yards.

Length times width will give you area. So this comes out to 81 square feet.

The length of a square with an area of 81 would be 9.

Multiply width by length to get the area. The answer would be 2754 square inches which is 19.125 square feet.

Let the length be 3x and the width be x: 3x*x = 243 3x2 = 243 Divide both sides by 3: x2 = 81 Square root both sides: x = 9 Therefore: length = 27 cm and width = 9 cm

9 x 9 = 81 it's area is 81 square units.

The area is 81 square units.

Area of a rectangle = 28/567 square ft or4/81 square ftArea = length * width= 7/9 * 4/63= 28/567 square ft or 4/81 square ft.

81 square inches.

Area of a square= Width x Height. Since all sides of a square are equal you can use the formula S2. Since you already know the area is 81, just take the square root which will give you 9.

They can be: 1 by 81, 3 by 27 and 9 by 9 as integers in cm

If the area is 81 square feet what is the perimeter?
