73 cm, the perimeter is all side totals, to to find each side length you just have to divide by 4 since all the sides of a square are the same
9/19 = x / 152....9 oz oil to 19 gallons gas = x oz oil to 152 gallons gas
cross multiply because this is a proportion
(19)(x) = (152)(9)
19x = 1368
x = 1368/19
x = 72 oz of oil <==
Not very much because things don't always happen the way we want them too
