You can put this solution on YOUR website!
For 2, You might want the dimensions of a room to be multiples of 20cm so that tiles do not have to be cut.
Do you want dimensions such that there are the same number of black and white tiles? This might be true for checkerboard. Are there other "nice patterns" ?
