7.25 until 8.00 = 35 minutes
8.00 until 3.00 PM = 7 hours
3.00 until 3.15 = 15 minutes
Answer is 7 hours 50 minutes
Find the total area of the room
109 * 103 = <span>11227 inches^2
the tile takes up 3*3 = 9 inches^2
11227/9 = </span><span>1247.4
You need 1247 tiles and 0.4 of a tile.
Or you could just get 1248 and cut the last tile a bit :P
Hope this helps :)</span>
No it is not due to 7 over 2 equals 3.5 making it rational.
