A non-square rectangle has integer dimensions. The number of square units in its area is triple the number of units in its perimeter. What is the smallest possible length for the perimeter?

Graphical solution shows   10 x 15   (or 15 x 10 )  rectangle.     So perimeter = 50 units

IF it was allowed to be a square (which it is NOT)  12 x 12 would be the answer  for a perimeter of 48
