A different angle (Posted on 2003-10-10) Difficulty: 3 of 5
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?

is it ab=5...bc=10...area is 100, perimeter 40.
sq root(absq+bcsq)=ac....sq root of 75 is 8.66 blah...it late but it sounds right...dont burn me if its wrong :-(
