Watson and the Mysterious Number One

Andy Samide


First paragraph: Clearly the number one could be used because the width of the rectangle would have a length less than the length of 4. But, if 2 were used instead of 1, the result would also give the width of the rectangle a length less than 4. So, how did Watson deduce that 1 would be the correct number to use for the problem? That is the mystery that puzzled the class and even Watson when he was asked to justify his use of the number one.
