You can put this solution on YOUR website!
S(n) = the number of tiles required.
\n" ); document.write( "The room is square (and assuming the tiles are square):
\n" ); document.write( "n = length of room in tile lengths = width of room in tile lengths
\n" ); document.write( "So Area of floor = n x n = n^2
\n" ); document.write( "So S(n) = n^2
\n" ); document.write( "The miniumum length of the room must be 1 tile length for it to be tileable, so domain: n>=1. Sorry for the edit.\r
\n" ); document.write( "\n" ); document.write( "This is my first answer I hope it's right and I hope it makes sense.
\n" ); document.write( "All the best. \n" ); document.write( "
