Take note that 1 meter = 1000 milimeters


So a 1 meter by 2 meter area is 1000 mm by 2000 mm. So multiply these two numbers to get 1000%2A2000=2000000. So the area is 2,000,000 square mm.


Now multiply 203 by 203 to get 203%2A203=41209. So the area of one tile is 41,209 square mm.

Now divide the total area by the area of one tile to get

2000000%2F41209=48.53


So rounding up, we need 49 tiles to cover the total area.
