Answer 1

`675`

Explanation:

GIVEN: new tiles are being laid in the school hallway the tiles measure
`1` foot by
`1` foot the hallway is
`75` feet long and
`9` feet wide.

TO FIND: how many tiles will be needed to cover the floor of the hallway.

SOLUTION:

as tile is square, area of one tile ​
`=\text{length}^2`

`=1^2=1\text{feet}^2`

as hallway is rectangular ,area of school hallway
`=\text{length}*\text{width}`

`=75*9`

`=675\text{ feet}^2`

number of tiles required
`=\frac{\text{area of hallway}}{\text{area of one tile}}`

`=(675)/(1)`

`=675`

Hence total
`675` tiles are required to cover the floor of hallway.
