Number of tiles to tile the room: 168 tiles
Number of tiles to tile the hallway: 48 tiles
Total number of tiles: 216 tiles
Step-by-step explanation:
To find how many tiles Vinyl needs, we need to find the total area of the room and the hallway, and divide these areas by the area of each floor tile.
The area of a rectangle is calculated with the product between its dimensions (length and width).
Area of floor tile = 1 ft2
Area of rectangular room: 12 foot * 14 foot = 168 ft2
Area of rectangular hallway: 12 foot * 4 foot = 48 ft2
Number of tiles to tile the room: 168/1 = 168 tiles
Number of tiles to tile the hallway: 48/1 = 48 tiles
Total number of tiles: 168 + 48 = 216 tiles
