A homeowner is planning to use carpet tiles to cover the floor of a room measuring in 10 feet
by 10 feet. If the carpet tiles are 8 inches wide and 1 foot long, and there are no gaps
between the tiles as they are placed on the floor, how many carpet tiles will the homeowner
need to cover the floor of the room?

C.
800
D.

I got 1,800 hope this helps

 B. 150 tiles

Step-by-step explanation:  First I would convert to same units, inches in this case...

each tile is 8 inches x 12 inches

room is 120 inches x 120 inches

then find area of each

8x12=96

120x120=14,400

see how many tiles fit in room

14,400/96=150

150 tiles

0.02
