Assuming you mean a rectangle: use the formula:p = 2(l+w)
(i.e., perimeter equals twice length plus width). In this formula, replace p with the known perimeter, and l with the given length, then solve for width.
you have to add all of the outside to get the perimeter of the answer.
The perimeter is two times the length plus two times the width. If you have two variables, solve for the third one.
P = 2L + 2 W
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 appying 2l+2w
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 :)
by appying 2l+2w
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.

It depends on the shape.
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
