I can't draw a picture here, I've uploaded a picture at http://www.cameronapartments.org/question.jpg - sorry i will be removing it after this question is resolved.

Given P and Y are midpoints, you will need to create an equation in terms of P and Y to find the area of the shaded region.

I know by logical thinking, when we combine the two triangles it will be 1/4 of the whole rectangle. Which means to find the shaded region, I just take the area of the whole triangle and minus off a quarter.

I forgot all my algebra, so my best guess (after 1 hour, LOL!) is that the simplest equation is:
PY - (PY/4)

If you substitute P and Y with numbers, it is correct too. But in terms of algebra, is the eqn correct? Is there a simpler or better equation?

LOL this is the funniest question I've ever asked!
