$\"A=L%2AW=14\"$
\n" ); document.write( " $\"W=L-5\"$
\n" ); document.write( "Substituting,
\n" ); document.write( " $\"L%2A%28L-5%29=14\"$
\n" ); document.write( " $\"L%5E2-5L=14\"$
\n" ); document.write( " $\"L%5E2-5L-14=0\"$
\n" ); document.write( " $\"%28L-7%29%28L%2B2%29=0\"$
\n" ); document.write( "Two solutions but only the positive solution makes sense here.
\n" ); document.write( " $\"L-7=0\"$
\n" ); document.write( " $\"L=7\"$
\n" ); document.write( "Then,
\n" ); document.write( " $\"W=7-5\"$
\n" ); document.write( " $\"W=2\"$ \n" ); document.write( "
