The floor of a rectangular room will be tiled with square tiles that measure 3 inches on each side. The room is 109 inches long and 103 inches wide. How many tiles, including parts of tiles, are needed to complete the job?

A. 1,248 tiles
B. 1,247 tiles
C. 1,224 tiles
D. 1,295 tiles
I think it is A but I am not sure..

109/3 = 36 1/3 so 37 in that direction

103 /3 = 34 1/3 so 35 in that direction

37 *35 = 1295

remember you will have some fractional tiles left over, but you need enough to reach the walls after trimming

I' m not on business I need help about how to Draw four ways to how the tiles can be arranged.

To calculate how many tiles are needed to cover the floor of a rectangular room, you need to determine the total area of the room and then divide it by the area of one tile.

In this case, the length of the room is given as 109 inches and the width is given as 103 inches. To find the area of the room, you multiply the length by the width:

Area of the room = Length × Width = 109 inches × 103 inches

Now, since the tiles are square and measure 3 inches on each side, the area of one tile is:

Area of one tile = Side length × Side length = 3 inches × 3 inches

To find the number of tiles needed, divide the area of the room by the area of one tile:

Number of tiles needed = Area of the room ÷ Area of one tile

Let's calculate it:

Area of the room = 109 inches × 103 inches = 11,227 square inches
Area of one tile = 3 inches × 3 inches = 9 square inches

Number of tiles needed = 11,227 square inches ÷ 9 square inches

Calculating, you find the number of tiles needed is approximately 1248.55. Since you cannot have a fraction of a tile, you can round up to the nearest whole number. Thus, you would need 1249 tiles.

Therefore, the correct answer is B. 1,247 tiles.
