\n" ); document.write( "given:
\n" ); document.write( " $\"S=4LW%2B2WH\"$
\n" ); document.write( " $\"S=168\"$
\n" ); document.write( " $\"L=9\"$
\n" ); document.write( " $\"W=4\"$ \r
\n" ); document.write( "\n" ); document.write( "start with $\"S=4LW%2B2WH\"$ , substitute given values\r
\n" ); document.write( "\n" ); document.write( " $\"168=4%2A9%2A4%2B2%2A4H\"$ ....solve for $\"H\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"168=144%2B8H\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"168-144=8H\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"24=8H\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"24%2F8=H\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"highlight%28H=3%29\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "now we can check it:\r
\n" ); document.write( "\n" ); document.write( " $\"S=4LW%2B2WH\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"168=4%2A9%2A4%2B2%2A4%2A3\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"168=144%2B24\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"168=168\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
