Mrs Thompson is putting new tile on her bathroom floor. Each tile measures 2 inches on each side. The bathroom floor is 3 feet long and 2 feet wide. How many tiles will she use to cover the entire floor?
Let's convert the feet to inches.
3 feet = 36 inches or 18 tiles
2 feet = 24 inches or 12 tiles
12 * 18 = ?
216
I seriously don't get how it would be 216 , but I did so accept that
To determine the number of tiles Mrs. Thompson will need, we first need to calculate the total area of the bathroom floor.
Given:
The length of the bathroom floor = 3 feet
The width of the bathroom floor = 2 feet
To find the area, multiply the length by the width:
Area = Length × Width
Area = 3 feet × 2 feet
Now, let's convert the area to square inches, as the size of each tile is given in inches:
1 foot = 12 inches
Area (in square inches) = (3 feet × 12 inches/foot) × (2 feet × 12 inches/foot)
Area = 36 inches × 24 inches
Next, we need to determine the area of one tile. The tile length and width are both given as 2 inches.
Area of one tile = Length × Width = 2 inches × 2 inches
Area of one tile = 4 square inches
To calculate the number of tiles required, divide the total area of the bathroom floor by the area of one tile:
Number of tiles = Area (in square inches) ÷ Area of one tile
Number of tiles = (36 inches × 24 inches) ÷ 4 square inches
Finally, calculate the result:
Number of tiles = 864 square inches ÷ 4 square inches
Number of tiles = 216 tiles
Therefore, Mrs. Thompson will need 216 tiles to cover the entire bathroom floor.
