Respuesta :
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
