The furthest I've gotten isA piece of wire of length 60 inches is cut into two pieces. One piece is foldedinto a square and the other into an equilateral triangle. Find the maximum of the area of the square

plus the area of the triangle. Choose the closest number from the list below.

$\displaystyle 60 = 4x + 3y $

PS, this is just for a test I'm taking online, I'm not even in a calculus class. Don't think I'm trying to cheat or anything.
