    length = 630

    width = 335

    Step-by-step explanation:

    p=1930

    width = 20+0.5*length

    length

    perimeter = 2*width + 2*length

    2 (20+0.5*length) + 2*length

    40+length+2*length

    40+3length=1930

    subtract 40

    3length=1890

    divide by 3

    length = 630

    plug in length to find width

    width = 335
