mathmale · Answer

@jeremyggg :  Yes, that sounds cool.
My only suggestion here is that we try re-drawing the diagram so that those right angles really look like right angles.  You dig me?

$$p^2=xy$$ Yes that is the formula. But I strongly suggest you to follow @jeremyggg  's method and finally remember this for your future reference.
