    Answer:

    l = 14.6 m

    b = 53.4 m

    Step-by-step explanation:

    Let breadth be x

    Let lenght be 4x-5

    so,

    perimeter = 2(l+b)

    136 = 2(4x-5+x)

    or, 136 = 2(5x-5)

    or, 136 = 10x – 10

    or, 136 + 10 = 10x

    or, 146 = 10x

    or, x = 146/10

    so, x = 14.6 m

    so, breadth(x) = 14.6

    so, lenght = 4x – 5

    = (4×14.6)-5r

    = 53.4m
