Best Answer

More information is needed. One of the sides or the diagonal length has to be known, unless you have a square, in which case you divide the perimeter by 4.

Perimeter minus two times the width will give you the two times the length. Area is found by multiplying the length by the width.

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

Length + length + width + width = perimeter. Length + width x 2 = perimeter

Perimeter = 2 * width + 2 * length, so rearranging --> width = (Perimeter / 2) - length

you need length and width length multiply width = area length + length + width + width = perimeter

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

you need length and width length multiply width = area length + length + width + width = perimeter

The perimeter is the total distance around - width + width+ length + length.

Perimeter = Width x 2 + length x 2. To find width, you minus the length from perimeter because opposite of ADD is SUBTRACT.

Length = (Perimeter - twice width) / 2

Length + width = half of perimeter, so you need more information...

You divide the perimeter by the width and you get the lenght
