    let length of the rectangle be l

    length is 6 cm longer than the width, w

    l = w + 6

    perimeter of rectangle is 72 cm

    = 2l + 2w

    substitute l = w + 6

    2 (w+6) + 2w = 72

    4w + 12 = 72

    4w = 60

    x = 15

    ans is C. 15 cm

    Step-by-step explanation:

    Perimeter = 2 x (length + width)

    72 = 2 x (l + w)

    Because l = w + 6

    72 = 2 x (w + 6 + w)

    = 2 x (2w + 6)

    = 4w + 12

    4w = 60

    w = 15 cm

    The answer is C.
