The length of a rectangle is twice its width if the area of the rectangle is 200 m squared, find its perimeter.

  • Math -

    A = Lw

    w = width
    2w = length

    200 = w(2w)
    200 = 2w^2
    100 = w^2
    10 = w

    P = 2L + 2w
    w = 10
    L = 2w = 20

    P = 2(10) + 2(20)
    P = ?
