If you have a single sub, place it at the midpoint of your front wall. If you have two subs, place each one a quarter of room width from the side walls. In either case, place your L/R speakers 2/3rds of room width apart (assuming you're using a centre speaker). The only way this will work is if the open doorway shown at the front left of your theatre room can be closed. If it is an open archway, then your room isn't really 11'2" wide and those placements won't work.
This will likely work for your first row (you'd have to measure to confirm), but not so much for the second row because the width of the bar area is having an influence at that point. Also, what is that light brown rectangle in the front right corner of your room?
