Consider a rectangular piece of paper ABCD with AB ≠ AD

Show how you can fold this piece of paper into five pieces of equal area.

*** Using any given instrument like straightedge, compass, protractor, ruler etc. is NOT permissible.

(In reply to re: a solution by Steve Herman)

My parenthetical note basically explains how to make pareallel creases:  make perpendicular ones and then fold perpendicular to these.

My method works equally well for squares and it doesn't matter which side is longer.

I think K S changed the problem to specify the rectangle was not a square when I mentioned the similarity to the very first puzzle I ever submitted here: http://perplexus.info/show.php?pid=2336
