Question

A room measures 12 feet by 12 feet. A couch is 10 feet and 6 inches long. If you center the couch in the middle of the room, how far will each end of the couch be from the nearest wall?

Answer 1

12(12)/2-(10(12)+6)/2

72-63

9"

So the ends of the couch will be 9 inches away from the wall closest to that end.
