    P=2 (L+W)

    120=2 (L+W)

    divide by 2

    60=L+W

    base=L

    height=W

    L is 3 times W

    L=3W

    60=3W+W

    60=4W

    divide by 4

    15=W

    sub back

    L=3W

    L=3 (15)

    L=45

    15 by 45

    the 2nd option (yo messed up with the lettering of choices, a, c, b, d)
