If you want the brick to be as large as possible, choose a brick with a side length of 5 decimeters to just finish 45 5 25 5
45 Bricks 45 square bricks with a side length of 5 decimeters are required.

50 30 = 1500 square decimeters.
Therefore, it is better to lay 5 decimeter tiles, in this case, you need to lay 60 tiles.
50 5 = 10 (block).
30 5 = 6 (block). >>>More
Now I didn't say anything about the unit of the decimeter, right? 5m long, wide, area is, a brick area is, block, damage rate in view of the area, just add 5 pieces, if there are too many gaps in the place, you need to add a few more, if you want a pattern of floor tiles, it is not easy to say.
The length is 3 decimeters, the width is 2 decimeters, and only one brick is enough! Because kitchen floor tiles are generally 300 300. Your question should be: the kitchen is 3 meters long and 2 meters wide, so it costs 70 bricks and 280 yuan!
It can be understood that the kitchen is a square, with a side length of 36 decimeters, 7 [(36 3) (36 2)] = 7 (12 18) = 7 216 = 1512, a total of 1512 yuan.
35*24 (2*2)=840 4=210 square bricks.
