If a 3'' by 3'' square is added at each successive stage, what will be the area of the rectangle at Stage 6, in square inches? [asy]size(250); real textsize = 10pt; draw(unitsquare); draw(shift(1.5*right)*unitsquare); draw(shift(2.5*right)*unitsquare); draw(shift(4*right)*unitsquare); draw(shift(5*right)*unitsquare); draw(shift(6*right)*unitsquare); label("Stage 1",(.5,0),S,fontsize(textsize)); label("Stage 2",(2.5,0),S,fontsize(textsize)); label("Stage 3",(5.5,0),S,fontsize(textsize));[/asy]

Each square measures 9in^2

So, at stage 6, we will have 6 x in^2 = 54in^2
