Type A is a bit complicated, and the rounded 4.8m×3.9m needs 16× 13=208 pieces.

The remaining gaps need to be filled with 2/3 or 1/3 tiles, and the drawing needs 15 tiles.

So a * * * costs 223 yuan, multiplied by 15 yuan each, and a * * * is 3345 yuan.

Class C is analyzed in a similar way, and rounding off 4.8m×4m requires 16×20=320 blocks.

The remaining 0.2m×4m needs 14.

Therefore, C * * * needs 334 yuan, multiplied by each 9.5 yuan, and a * * * is 3 173 yuan.

Therefore, it is more cost-effective to choose C floor tiles.

If you consider the pattern of the floor tiles to be connected, the wages of the workers' masters and other factors, it is a little more complicated, and you can discuss it if you are interested.
