Best Answer

Perimeter = 2*L + 2*W

Area = L*W

L = Area / W

Perimeter = 2*Area / W + 2*W

W * Perimeter = 2*Area + 2*W^2

Let A=area, and P= perimeter.

0=2W^2-PW+2A

W= (P + root(P^2-16A))/4

or

W= (P - root(P^2-16A))/4

Once you have W,

L is simply A/W.

Have fun, and maybe include some numbers to work with next time.

If you know the area the divide area by length if you know perimeter subtract it by 2xlength and divide by 2

You have to add up all the sides of the shape.

It not possible you nit witt that is not true length x width = area If you know length and area, solve width width = area / length then 2 x length + 2 x width = perimeter

You only need to know the length of one side. Knowing the side length (s) you can find the area (multiply s by s) and perimeter (multiply s by 4)

There is no possible way to. You can only add up all the sides to get the perimeter.---It is not impossible. You can get the perimeter from area very easily.First, you find the square root of the area, which will be the length of each side (assuming it is a square).Then, once you've found the length of each side, you multiply it by 4, and you should have the perimeter.

You can find the perimeter of a rectangle if you know its area and the length of one side. Divide the area by the length of the known side and the quotient will be the length of a side perpendicular to the known side, and then multiply the sum of the two sides by two to find the perimeter.

Divide the perimeter by 4 and then square the result to find the area of the square.

Perimeter equals to 2 times the length plus 2 times the breadth. Area equals to length multiply by breadth

If you know the area the divide area by length if you know perimeter subtract it by 2xlength and divide by 2

You can't only using the perimeter. You have to know length and width.
