The length of a rectangular garden is 4 yards more than the width. The area of the garden is 60 square yards. Find the dimensions of the garden.

  • Math -

    Width = W yards.
    Length = (W+4) yards.

    A = (W+4)W = 60.
    W^2 + 4W - 60 = 0
    C = -60 = -6*10
    (w-6)(w+10) = 0

    W-6 = 0
    W = 6

    W+10 = 0
    W = -10.
    Use the positive value for W:
    W = 6 Yds.
    L = W+4 = 6+4 = 10 Yds.
