You can put this solution on YOUR website!
x and y for original length and breadth;
A, the same area for original and new rectangles

system%28x=y%2B3%2CA=xy%29


New rectangle has dimensions x+9 and y-5 for length and breadth.
A=%28x%2B9%29%28y-5%29

Maybe you can do the algebra and arithmetic steps from here. You could start buy substituting for x into both A equations, and then simplify them.
