Question

A formula for finding the perimeter of a rectangle is p=2l+2wp=2l+2w. if you know the perimeter (p)(p) and width (w)(w) of a rectangle, which formula can you use to find the length (l)(l)?

Answer 1

p=2L+2W

L=(p-2W)/2

.................

Answer 2

Answer:
`(p)/(2)-w`

Explanation:

Given : A formula for finding the perimeter of a rectangle is
`p=2l+2w`.

To derive the formula for length (l), we first need to subtract 2w on both sides, we get

`p-2w=2l`

Divide both sides by 2 , we get

`l=(p-2w)/(2)=(p)/(2)-w`

Hence, the formula can you use to find the length (l) =
`(p)/(2)-w`
