GC #3 hints and answers

There are two rectangles with whole-number dimensions whose perimeter is the same number as its area. Find both rectangles.


There are many approaches to this problems - one is to make systematic guesses at what the answers might be, and then figure out how to adjust them so that the perimeter and area come closer together. As always, be sure to explain the work you did to arrive at your answers!
