A rectangular sheet of paper is folded so that two diagonally opposite corners come together. The crease thus formed is as long as the longer side of the rectangle.

What is the ratio of the longer side of the rectangle to the shorter?

Although I still think my general reasoning was right, I now get:

√((√5 + 1)/2)

as the final answer. (In other words, I think that I screwed up the computation before!)
