Define some variables first.
\n" ); document.write( "\"L\"-length
\n" ); document.write( "\"W\"-width
\n" ); document.write( "Turn the words into equations.
\n" ); document.write( "\"11 feet longer than it is wide\"
\n" ); document.write( "1.\"L=11%2BW\"
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( "The area of a rectangle is,
\n" ); document.write( "\"A=L%2AW\"
\n" ); document.write( "2.\"L%2AW=276\"
\n" ); document.write( "Substitute using eq. 1,
\n" ); document.write( "\"%2811%2BW%29W=276\"
\n" ); document.write( "\"W%5E2%2B11W=276\"
\n" ); document.write( "\"W%5E2%2B11W-276=0\"
\n" ); document.write( "Factor,
\n" ); document.write( "\"%28W%2B23%29%28W-12%29=0\"
\n" ); document.write( "Two solutions but only the positive solution makes sense in this case.
\n" ); document.write( "\"W-12=0\"
\n" ); document.write( "\"highlight%28W=12%29\"ft
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( "Then from eq. 1,
\n" ); document.write( "\"L=11%2B12\"
\n" ); document.write( "\"highlight%28L=23%29\"ft
\n" ); document.write( "
\n" );
