    45 feet by 39 feet

    Step-by-step explanation:

    l = length

    w = width

    Perimeter, p of a rectangle = 2 (l + w)

    and p = 168 feet

    but l = 6 + w

    substitute the value of l

    168 = 2 ((6 + w) + w)

    168 = 2 (6 + w + w)

    168 = 2 (6 + 2w)

    expand

    168 = 12 + 4w

    subtract 12 from both sides

    168 - 12 = 4w

    156 = 4w

    divide both sides by 4

    39 = w

    substitute the value of w in l = 6 + w

    l = 6 + 39

    l = 45

    Hence, the dimensions are 45 feet by 39 feet
