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

By forming a quadratic equation from the information given and then the length and width can be found by solving the equation.
It depends on the shape.
Multiply length by width
Length = (Perimeter - twice width) / 2
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
If you are given the width and the perimeter, then figure out what the length is then calculate the area... hope this helps :)

Perimeter = 2*(L + W).
width = (perimeter-2*length)/2
By forming a quadratic equation from the information given and then the length and width can be found by solving the equation.

Multiply length by width
Length + length + width + width = perimeter. Length + width x 2 = perimeter
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
Perimeter = 2 * width + 2 * length, so rearranging --> width = (Perimeter / 2) - length
