If I'm correct, the area of a square, or any rectangle (a square is also a rectangle) = side x side.
Since all sides of a square are = to each other, the area of a square = length of one side, squared.
So you'd need the square root of 81 to find the length of one side = 9. Perimeter of an object is the sum of it's sides. Square has 4 sides, so 9+9+9+9 = 36
Area of square = 81 cm2 so side of square = 9 cm and then perimeter = 4*side = 36 cm.
The length of a square with an area of 81 would be 9.
The area is 9 feet. You find the square root of 81 which is 9. I want circumference, not area.
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.
9
Area of square = 81 cm2 so side of square = 9 cm and then perimeter = 4*side = 36 cm.
Use your calculator to calculate the square root of 81. Or use trial-and-error, to see which number, when multiplied by itself, gives you 81. (Hint: In this case, it is an integer.)
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.
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.
The length of a square with an area of 81 would be 9.
9 x 9 = 81 it's area is 81 square units.
The area is 81 square units.
81 square inches.
If the area is 81 square feet what is the perimeter?
Area of circle: 81*pi square units
81 square feet (9 x 9 = 81).
