 A different angle (Posted on 2003-10-10)
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?

First of all, according to my calculations, 12 and -20/3 are the solutions to your equation, not 56.

Second of all, the hypoteneuse of a right triangle is never equal to one of its legs!
