A worker is tiling the floor of a rectangular room that is 12ft by 15ft. The tiles are square with side lengths 1 1/3 feet. How many tiles are needed to cover the entire floor.
PLS HELP, I NEED A PASSING GRADE! :(
12 * 15 / (4/3)
To find the number of tiles needed to cover the entire floor, we need to determine the total area of the floor and divide it by the area of each tile.
First, let's calculate the area of the floor.
Area of the floor = Length × Width
Area = 12 ft × 15 ft
Area = 180 square feet
Now, let's calculate the area of each tile.
Area of the tile = Length × Width
Area = (1 1/3 ft) × (1 1/3 ft)
Area = (4/3 ft) × (4/3 ft)
Area = 16/9 square feet
To find the number of tiles needed, we divide the total area of the floor by the area of each tile:
Number of tiles = Area of floor ÷ Area of each tile
Number of tiles = 180 square feet ÷ (16/9 square feet)
Dividing the areas, we get:
Number of tiles = 180 sq ft × (9/16)
Number of tiles = 45 tiles
Therefore, to cover the entire floor, you will need 45 tiles.
