--------------
12 by 12 must mean the floor of the stall.
What part is in the frame depends on the location relative to the floor and the focal length.
If it's above the center of the floor 9' up, and 63 degs is the included angle, it will cover a circle 5.52' in diameter. Not all of the floor.
------------
To view all of the floor, it would have to be 13.85' above it.
