    The correct answer is: Length of the rectangle = L = 5.7 ft

    Explanation:

    The perimeter of a rectangle is given as:

    P = 2 * (L + W) - - - (1)

    Where,

    P = Perimeter = 27.2 ft

    L = Length = ?

    W = Width = 7.9 ft

    Plugin the values in equation (1):

    (1) = > 27.2 = 2 * (L + 7.9)

    L = (27.2 - 15.8) / 2

    L = 5.7 ft

    Hence the length of the rectangle is 5.7 ft. (where ft = feet)

    2 (l + b) = 27.2

    2 (l + 7.9) = 27.2

    2l + 15.8 = 27.2

    2l = 11.4

    l = 5.7 ft
