    Answer:

    Width=11

    Length=16

    Step-by-step explanation:

    P=2L+2W

    54=2(5+w)+2w

    Open the brackets

    10+2w+2w=54

    10+4w=54

    Collect the like terms

    4w=54-10

    4w/4w=44/4

    W=11

    Since the length is 5m longer

    Therefore:11+5=16

    Width=11

    Length=16
