Area of each tile is $\"15%2A15+=+225\"$ cm2
\n" ); document.write( "(area of floor) / (area of 1 tile) = number of tiles needed
\n" ); document.write( "I must convert floor dimensions to cm
\n" ); document.write( " $\"5.4%2A100+=+540\"$ cm
\n" ); document.write( " $\"4.05%2A100+=+405\"$ cm
\n" ); document.write( " $\"540%2A405+=+218700\"$
\n" ); document.write( " $\"218700+%2F+225+=+972\"$ tiles \n" ); document.write( "

\n" );
