The floor area is 30 ft x 18 ft, or $\"540+ft%5E2\"$ .
\n" ); document.write( "The area of each square tile is $\"3ft%2F2+%2A3ft%2F2=+9ft%5E2%2F4\"$ .
\n" ); document.write( "Let x = number of tiles needed to cover $\"540+ft%5E2\"$ of floor area.
\n" ); document.write( "Then $\"9%2F4%2Ax+=+540\"$ .
\n" ); document.write( " $\"x+=+540%2A4%2F9\"$
\n" ); document.write( " $\"x=240\"$ \n" ); document.write( "
