Is there a way to dimension the area of a rectangle or other closed object?

I know you can easily dimension a line by using the smart dimension tool.  Is there a way to quickly dimension the area of a rectangle or any other closed polygon?   I know how to use the "GETAREA" command and I will get the area measurement in the command line, however I want to place this area on the drawing.  I'm looking at a floor plan of a building and trying to take off the area of each room.

Thanks,

Jason
