    96 meters

    Step-by-step explanation:

    First set up

    length*width=Area

    (5w) * (w) = 320

    5w^2=320

    w^2=64

    w=8

    Now, find the perimeter.

    Side1+Side2+Side3+Side4 = Perimeter

    5w+w+5w+w = P

    12w = P

    Now Substitute your w (width)

    12 (8) =

    96 meters
