    Step-by-step explanation:

    Let, breadth = x

    So,length = x + 4

    Perimeter of rectangle = 2(l + b)

    60m = 2(x + x + 4)

    60m = 2 X 2x + 4

    60m ÷ 2 = 2x + 4

    30m = 2x + 4

    30m- 4 = 2x

    26m = 2x

    26m ÷ 2 = x

    13m = x

    So,

    BREADTH = 13m

    LENGTH = x + 4

    = 13m + 4

    = 17m
