    Answer:79.2x19.8

    Step-by-step explanation:

    Length (L) = 4xwidth (w) L=4w

    Perimeter (p) = 198

    P=2L+2w 2L+2w=198

    Substitute L=4w in 2L+2w=198

    2 (4w) + 2w=198

    8w+2w=198

    10w=198

    w=198/10

    w=19.8

    Substitute w=19.8 in L=4w

    L=4x19.8

    L=79.2
