If the shape is a rectangle, then Perimeter = 2(Length + Width) So Width = Perimeter/2 - Length

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

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
