Length = Width = 9 units.
If it has an area of 81 square units it could be 1 unit x 81 units giving a perimeter of 2 x (1 + 81) = 164 units;It could be 3 units by 27 units giving a perimeter of 2 x (3 + 27) = 60 units;There are many other possibilities, most with non-whole number lengths of the sides.
If the area is square than we just find the square root of 81,which is 9 feet x 9 feet.Or if it is a Rectangle we could divide 81 by 18 to get 18 feet x 4.5 feet.If the area is a circle we will multiply 81 by PI, then take the square root multiplied by two. In that case it would equal a circle 10.1 feet in diameter.If the area was a triangle the dimensions could be 9 feet by 18 feet by 20.1 feet (altitude, base, hypotenuse).
If the area is 81 square feet what is the perimeter?
Using 3.14 as Pi the area of circle is: 2.5434
81 square feet (9 x 9 = 81).
Area of circle: 81*pi square units
The area is 81 square units.
81 square units Actual area 80.6404 square units
9 x 9 = 81 it's area is 81 square units.
A square with a side length of 9 units has an area of 81 square units.
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 units
The area of square is : 81.0
The sides of the square will each measure 9 units
It is: 9/10*9/10 = 81/100 or 0.81 square units
9+9+9+9 = 36 units
Length = 9 Width = 9 Your rectangle is a square.
