    Answer:

    19 units

    Step-by-step explanation:

    Perimeter of the rectangle = 124 units

    width = x units

    length = 5 + 2x units

    The perimeter of a rectangle is given by;

    P = 2(l + b)

    Substituting values;

    124 = 2[(5 + 2x) + x]

    124 = 2[5 + 3x]

    124 = 10 + 6x

    124 – 10 = 6x

    114 =6x

    x= 114/6

    x = 19

    width = 19 units
