"The area of a rectangle is 360m2. If its lengh if increased by 10m and its width is decreased by 6m, then its area does not change. Find the perimeter of the original rectangle." I need to use the "guess and test" or the "draw a diagram" method to solve; which would be most useful, and how would you go about solving the problem in general?
