    So,

    w = width

    2w = length

    The perimeter is the sum off all the sides of the rectangle

    P = w + w + l + l = 2w + 2l

    Using our terms and the value of 60, substitute them into the equation.

    60 = 2w + 2 (2w)

    60 = 6w

    w = 10 ft

    l = 2w = 20 ft

    Checking our solution:

    60 ft = 10 ft + 10 ft + 20 ft + 20 ft

    60 ft = 60 ft

    Now onto the area, the area of a rectangle is the product of its dimensions and is given by the formula

    Area = l*w

    substituting our values in from above

    A = (20 ft) * (10 ft) = 200 ft 2
