Programming Enigma Puzzles

17 January 2012

Posted by on **From New Scientist #2759, 8th May 2010** [link]

I drew a square whose sides were an integral number (less than 80) of centimetres long. Within the top left-hand quarter of the square I marked four points, each of which was an integral number of centimetres, not only from each side of the square but also from both the top left-hand corner and the bottom right-hand corner of the square.

How long was each side of the square?
