each kitchen floor tile is 12 inches by 12 inches.a kitchen floor needing to be tiled is in the shape of a rectangle measuring 12 ft by 16 ft. how many tiles are to cover the kitchen floor?
A = 12 * 16
A = 192 square feet = 192 - 12" by 12" tiles
42 tiles
189ft2
To find out how many tiles are needed to cover the kitchen floor, we need to calculate the total area of the floor and then divide it by the area of each tile.
Step 1: Convert the measurements to the same unit.
The dimensions of the kitchen floor are given in feet, while the tile dimensions are in inches. Let's convert the dimensions of the kitchen floor from feet to inches.
12 ft = 144 inches (since 1 ft = 12 inches)
16 ft = 192 inches
Step 2: Calculate the area of the kitchen floor.
The area of a rectangle can be found by multiplying its length and width.
Area = Length x Width
Area = 144 inches x 192 inches
Area = 27,648 square inches
Step 3: Calculate the area of each tile.
Since each tile is 12 inches by 12 inches, the area can be found by multiplying these dimensions.
Area of tile = 12 inches x 12 inches
Area of tile = 144 square inches
Step 4: Determine the number of tiles needed.
To find the number of tiles needed, divide the total floor area by the area of each tile.
Number of tiles = Total floor area / Area of each tile
Number of tiles = 27,648 square inches / 144 square inches
Number of tiles ≈ 192 tiles
Therefore, approximately 192 tiles are required to cover the kitchen floor.
