State the formula to find the length of a rectangle given the perimeter

Answer 1

P = 2(L + W)

P / 2 = L + W

(P / 2) - W = L

Answer 2

The perimeter of a rectangle is just twice the length plus twice the width or Perimeter = 2•L + 2•W, so rearranging to solve for the length gives:

(P – 2•W) ÷ 2 = L
