    Answer:

    c)62.5cm and 37.5cm.

    Step-by-step explanation:

    the ratio of parallelogram=5x:3x

    perimeter of parallelogram=200cm

    let the length of Parallelogram=5xcm

    let the breadth of the parallelogram=3xcm

    perimeter of parallelogram =2(L+B).

    2(L+B)=200

    2(5x+3x)=200

    2(8x)= 200

    16X=200

    X=200/16

    X=12.5

    taking x in breadth and length

    5x=5×12.5=62.5

    3x=3×12.5=32.5

    there fore length=62.5cm

    breadth=32.5Cm

    Answer:

    the correct option is C

    Step-by-step explanation:

    let the ratio of parallelogram =x

    =5x:3x

    perimeter of parallelogram =2(L+B)

    Putting the length and breadth

    2(5x+3x)=200

    2(8x)=200

    16x=200

    x=200/16

    x=12.5

    Putting value of x in length and breadth

    5x=5×12.5=62.5

    3x=3×12.5=37.5

    So the length is 62.5cm and

    breadth is 37.5cm.
