    Answer:

    length =50

    breadth=40

    Step-by-step explanation:

    let us consider the number as x

    so length is 5x

    breadth is 4x

    2(l+b)=180

    2(5x+4x)=180

    2(9x)

    18x=180

    x=10

    therefore,

    length =5x=5^10

                       50

    breadth=4x=4^10

                        40

    Answer:

    50m and 40 m

    Step-by-step explanation:

    ratio= 5:4

    perimeter= 180 m

    perimeter= 2(l+b)

    180= 2(5x+4x)

    180=2×9x

    180=18x

    18x=180

    x= 180/18

    x=10

    Length= 5x=5×10=50 m

    Breadth= 4x=4×10=40 m
