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?
Good man, i missed the fact that the area is only 3/4 of the square...well done mate!
