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
