You want to install kitchen floor tiles that each measure 12 inches by 12 inches (1 sq. foot). Your kitchen measures 12 feet by 14 feet, but there is a 2 foot by 4 foot area around the sink that will not be tiled. How many tiles do you need?

12 * 14 = 168 square feet
2 * 4 = 8 square feet

I'm sure you can figure the number tiles needed from here. We'll be glad to check your answer.
Would that be 12' x 14' = 168 sq ft to be floored. But 2' x 4' = 8 sq. ft not floored. Therefore, 168-8 = 160 sq ft to be floored. Since each tile is 1' x 1', we will need 160 sq ft/1 sq ft = ?? tiles. Check my work. Check my thinking.
