For a rectangle,
\n" ); document.write( " $\"A=L%2AW=143\"$
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( " $\"L=W%2B2\"$
\n" ); document.write( "Substitute,
\n" ); document.write( " $\"%28W%2B2%29%2AW=143\"$
\n" ); document.write( " $\"W%5E2%2B2W=143\"$
\n" ); document.write( " $\"W%5E2%2B2W-143=0\"$
\n" ); document.write( " $\"%28W-11%29%28W%2B13%29=0\"$
\n" ); document.write( "Only use the positive solution,
\n" ); document.write( " $\"W-11=0\"$
\n" ); document.write( " $\"W=11\"$
\n" ); document.write( " $\"L=W%2B2=13\"$
\n" ); document.write( "The window is 11' wide and 13' long.
\n" ); document.write( " \n" ); document.write( "

\n" );
