\n" ); document.write( "By direct substitution, $\"2%2A%281.4W%29+%2B+2W+=+33\"$ .
\n" ); document.write( " $\"2.8W+%2B+2W+=+33\"$ ,
\n" ); document.write( " $\"4.8W+=+33\"$ ,
\n" ); document.write( " $\"W+=+6.875\"$ meters.
\n" ); document.write( "The length of the room is 9.625 meters. \n" ); document.write( "
