The perimeter of a rectangle in units equals its area in units squared. (4,4), (3,6), and (6,3) are three possible pairs of lengths for this rectangle.
Give another pair of positive integral sides for this rectangle or prove why there isn't another pair.

Another way of thinking about this by John Reid)
Well John,
I, for one, find your solution interesting (and very clear), and in some ways more elegant than what I offered.
I hope other people are encouraged to propose alternative solutions as well.
Thanks,
