You can put this solution on YOUR website!
L for length
\n" ); document.write( "w for width\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"L+=+6w\" and \"2%28L%2Bw%29=42\" directly from the description.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Substituting for L in the perimeter equation, \"2%28%286w%29%2Bw%29=42\"
\n" ); document.write( "\"12w%2B2w=42\"
\n" ); document.write( "\"14w=42\"
\n" ); document.write( "\"highlight%28w=3%29\" meaning that \"highlight%28L=18%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Your mistake was from:
\n" ); document.write( "\"2%286%2Aw%29%2B2w=42\"
\n" ); document.write( "Which should have gone,
\n" ); document.write( "\"2%2A6w%2B2w=42\"
\n" ); document.write( "\"12w%2B2w=42\"
\n" ); document.write( "\"14w=42\", and as shown already...
\n" ); document.write( "
\n" );
