You cannot.
First of all you need to assume that the figure in question is a quadrilateral and not a triangle of polygon with 5 or more sides. Even so, for a given perimeter there are infinitely many combinations of length and width.
Here is an illustration, using perimeter = 12 units
(L,W) = (3,3), (3.1,2.9), (3.01,2.99)
In general, L = any number, rational or irrational, between 3 and 6 and W = 6-L will result in the perimeter being 12.

What is the formula to find the length of a rectangle when the perimeter and width is already given?
Length = (Perimeter - twice width) / 2
How do you find area when given perimeter and width?
If you are given the width and the perimeter, then figure out what the length is then calculate the area... hope this helps :)
Find the perimemter of a rectangle with length 15 meters and width 10 meters?
The perimeter of a rectangle is given by:P = 2l + 2w, where P is the perimeter of the rectangle, l is the length of the rectangle, and w is the width of the rectangle.P = 2(15) + 2(10) = 50 meters.
How do you find the length and width and the area is given?
If the area is already given, there should also be either width or length given. Do the area, divided by the length or the width. For example, the area divided by the width equal the length. Hope it helps.
If you know a perimeter of a square but not the length or width how do you find the area?
Divide the perimeter by 4 and then square the result to find the area of the square.
What is the formula to find the length of a rectangle when the perimeter and width is already given?
Length = (Perimeter - twice width) / 2
How do you find the length of a rectangle if the perimeter is 40 and the width is 2inches?
perimeter = 2 x (length + width) ⇒ length + width = perimeter ÷ 2 ⇒ length = (perimeter ÷ 2) - width So to find the length of the given rectangle, subtract the width from half the perimeter is how to do it. IF you meant "What is the length..." then: length = perimeter ÷ 2 - width = 40 ÷ 2 - 2 in = 20 - 2 in = 18 in
How do you find area when given perimeter and width?
If you are given the width and the perimeter, then figure out what the length is then calculate the area... hope this helps :)
How do you find the length and width of rectangle when given the perimeter but not the width or length?
by appying 2l+2w
How do you find the perimeter of a rectangle given the length and width?
Perimeter = 2*(L + W).
How do you find width when you have perimeter and length?
width = (perimeter-2*length)/2
How do you find the length and width of a rectangle when given the area and perimeter?
By forming a quadratic equation from the information given and then the length and width can be found by solving the equation.
How do you find Length and width whe area and perimeter are given?
It depends on the shape.
How do you find the optimal area of a rectangle given its perimeter?
Multiply length by width
What is one different way to to find the perimeter of a rectangle?
Length + length + width + width = perimeter. Length + width x 2 = perimeter
How do you find the perimeter of a rectangle with only the width or length and the area given?
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
How do you find the width of a rectangle if you know the perimeter and the length?
Perimeter = 2 * width + 2 * length, so rearranging --> width = (Perimeter / 2) - length
