Answer: The number of tiles that will take to cover a floor is 24000
Step-by-step explanation:
We are given:
Dimensions of rooms = 150 ft × 90 ft
Dimensions of 1 tile = 9 inch × 9 inch
Converting foot into inches, we get:
1 foot = 12 inches
So, dimensions of room = [tex](150\times 12)inch\times (90\times 12)inch[/tex]
To calculate the number of tiles, we divide the dimensions of room by the dimensions of 1 tile:
[tex]\text{Number of tiles}=\frac{\text{Dimensions of room}}{\text{Dimension of 1 tile}}[/tex]
Putting values in above equation, we get:
[tex]\text{Number of tiles}=\frac{(150\times 12)\times (90\times 12)}{9\times 9}\\\\\text{Number of tiles}=24000[/tex]
Hence, the number of tiles that will take to cover a floor is 24000
