splitting it evenly among all three sides gives us the greatest area. ( for example if we had to split the number 10 into 2 and find the greatest area, out of all possible ways 5*5 is the greatest). Two sides have to be equal since it's a rectangle.
918/3=306
So we can make the two equal sides 306, and the longer side 308 which makes sure that we have the greatest area.
