Question

How many 9" x 9" tiles will it take to cover the floor if a room hs the dimensions of 150' x 90' ?

Answer 1

Answer: The number of tiles that will take to cover a floor is 24000

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 =
`(150* 12)inch* (90* 12)inch`

To calculate the number of tiles, we divide the dimensions of room by the dimensions of 1 tile:

`\text{Number of tiles}=\frac{\text{Dimensions of room}}{\text{Dimension of 1 tile}}`

Putting values in above equation, we get:

`\text{Number of tiles}=((150* 12)* (90* 12))/(9* 9)\\\\\text{Number of tiles}=24000`

Hence, the number of tiles that will take to cover a floor is 24000
