Look at this shape:
Assume AB = AF = FE = ED and BC = CD, and all the angles in the shape are 90 degrees.
Let A be the area of this shape (in cm^2), and P -- the perimeter of this shape (in cm).
If A - P is 60, what is the length of line AC?
I have had several third parties who have thought this one through... after i gave them the print out of the puzzle and they all came to the same answer as i did (on my second send)...are you saying this is still unsolved? Let me know one way or the other!
