The length of a rectangle is twice its with. The are is 128yd^2. Find the length and the Width

  • Algebra II -

    L = Length

    W = With

    A = Area


    L = 2 W


    A = L * W

    A = 2 W * W

    A = 2 W ^ 2

    128 = 2 W ^ 2 Divide both sides with 2

    64 = W ^ 2

    W = sqrt ( 64 )

    W = 8 yd

    L = 2 W = 2 * 8 = 16 yd


    A = L * W = 8 * 16 = 128 yd ^ 2
