    The perimeter of a rectangle is twice the sum of the length and width:

    P = 2 (L + W)

    Since we are given L > = 50 ft and P = 140 ft:

    140 > = 2 (50 + W)

    70 > = 50 + W

    20 > = W

    Therefore, the width is less than or equal to 20 ft.

    (The maximum area is 50 x 20 = 1000 ft^2.)
