    Answer:

    given

    area= 400 m sq.

    _______________________

    to find-

    length

    breath

    _________________________

    solution-

    let length be l cm and breath be b cm.

    lenght= 2 x breath

    area= lenght x breath

    area = 2b x b

    400= 2b^2

    b^2= 200

    b= √200

    b= 10√2 cm

    lenght= 2 x 10√2= 20 cm

    Answer:

    let the bredth be x

    and the length will be 2x

    here

    according to the question

    x×2x=400 m²

    =>2x²=400m²

    =>x²=200m²

    =>x=√200m

    so x= √200

    so the length is 2√200m

    and the bredth is √200m
