B. 1,247 tiles

Step-by-step explanation:

Given :

The length of the rectangular room = 109 inches,

Its width = 103 inches,

Since, the area of a rectangle = Length × Width,

Thus, the area of the floor = 109 × 103 = 11227 in²,

Now, the side of a square tile = 3 inches,

And, The area of a square = (Side)²,

So, the area of the tile = (3)² = 9 in²

Hence,

Hence, 1247 tiles are needed.
