I have the following story problem and I dont know how to solve it. Here it is: You are tiling a room in your home that measures 18 feet long by 12 feet wide. Each square tile has an area of 324 square inches. What are the dimensions of a tile? How many tiles will you need to cover the floor? HELP PLEASE!!!
18ft=216inch 12ft=144inch room's area = 216*144=644.972.544 square inches So, if 1 tile is 324 square inches, you will need 644.972.544/324=1990656 tiles
tile's width = tile's length = sqrt(324)=18 so the tile is 18x18
