$\"p=+2%28l%2Bw%29=40\"$ ......eqn 1
\n" ); document.write( " $\"w=+l%2F2+-1\"$
\n" ); document.write( "substitutiong w in eqn 1
\n" ); document.write( " $\"2%28l%2B+l%2F2+-1%29+=40\"$
\n" ); document.write( " $\"2l+%2B+l+-2+=+40\"$
\n" ); document.write( " $\"3l=40%2B2\"$
\n" ); document.write( " $\"3l%2F3=42%2F3\"$
\n" ); document.write( " $\"l=14\"$ ft
\n" ); document.write( "so $\"w=+l%2F2-1\"$ = $\"14%2F2-1\"$ = $\"6\"$ ft \n" ); document.write( "

\n" );
