100 ft.^2
10 ft * 10 ft = 100 sq ft.
140 sq. ft.

15 x 10 = 150 (sq ft).
10 ft x 8 ft = 80 square feet.

150 ft^2
A 48ft by 10ft room is 480 square feet
10 ft x 20 ft room = 200 square feet
1000 square feet
The units of measurement for neither the tile nor the room are given. I can therefore assume that it is a 10 ft x 10 ft room and a 12 ft by 12 ft [carpet] tile. So answer: less than 1 tile.
