iGUIDE Report and PDF floor plans include this note: "Only major rooms are listed. Room dimensions are largest width and length, parts of room may be smaller. Room area is interior area and excludes footprint of walls."

Floor plans display arrows that indicate how every room dimensions are measured. Multiplying room width and length will not result in room floor area, unless the room has simplest rectangular shape. 

Only major rooms have their dimensions and floor areas listed by default and adding up their floor areas will not result in total floor area of the floor. If you would like to display measurements for other rooms that were not originally enabled in the iGUIDE you can activate them in the iGUIDE Portal in the iGUIDE editor.
