    Answer:

    length= 7m and breadth= 21m

    Step-by-step explanation:

    Perimeter=56m

    Perimeter of a rectangle= 2(l+ b)

    Dimensions in the ratio 1:3

    1:3= 1x and 3x

    Take length as 1x and breadth as 3x

    2(1x+3x)= 56m

    2(4x)= 56

    8x=56

    x= 56/8 = 7m

    length= 1x= 7m

    breadth= 3x= 3*7 = 21m
