Mr Snider is tiling a floor. The floor is 16 tiles long and 9 tiles wide. The center section is 12 tiles long and 5 tiles wide. How many tiles are in the border section?

If the whole floor has 144 tiles in it with 60 tiles being the middle section, then that must mean that there are 84 tiles in the border section
