<h3>How to find the number of tiles?</h3>
The first thing to do is the find the area of the rectangular hallway to know the area that needs to be covered:
Area = Length x Width
Area = 24 x 15
= 360 feet²
The dimensions of the tiles in feet is:
= 6 / 12 inches per feet
= 1/2 feet
The area of the tiles in feet is:
= 1/2 x 1/2
= 1/4 feet ²
The number of tiles needed is:
= Area of hallway / Area of tiles
= 360 / (1 / 4)
= 1, 440 tiles
