    HI!

    Here’s your answer:

    Let the length = x

    Let the breadth = y

    Area = xy = 400 sq. m

    Perimeter = 2(x + y) = 80m

    x + y = 40

    x = 400/y

    400/y + y = 40

    401 = 40y

    y = 401/40 = 10.025m

    x = 400/10.025 = 80/2.005 = 80000/2005 = 16000/401 = 39.9……..

    Therefore, it is not possible.

    hope it helped you!
