A silly little ratio problem for you

I was wandering around the SmartBoard website and I came across this little bit of information:
Model  Active screen area
690  94" (238.8 cm), 16:9 aspect ratio
685  87" (221.0 cm), 16:10 aspect ratio
If that 94" is the diagonal of the active area, what are the dimensions of the whole board? Let's assume it's 3" from the active area to the actual edge of the equipment on the left, top and right and 6" at the bottom (to include the "chalk tray").

How about for the 87"?
