109 *103 = 11227 square inches

tile = 3^2 = 9 square inches

11227/9 = 1247.44 tiles are needed.

 you can't buy a partial tile so you would need 1248 tiles

Answer:

We need 1248 tiles to complete the job.

Step-by-step explanation:

First we have to get the area of the  room and the area of each tile

Area = long x wide

Room Area = 109 x 103 = 11227 square inches

Tile area = 3 x 3 = 9 square inches

To get how many tiles we need, we must divide the room area by the tile area

Q=11227/9= 1247,44 ≅1248
