546*714 /(42*42) = 221
but, is that exact?
546 / 42 = 13
714 / 42 = 17
yes, tiles do not have to be cut.

You will need 221 tiles.
546 x 714 = 389,844cm
42 x 42 = 1,764cm
389,844 / 1,764 = 221 cm
Double-check:
1,764 x 221 = 389,844
So yes, you will need 221 tiles to fill 389,844cm in a rectangular area. I hope this helps! :)
