\n" ); document.write( " $\"Perimeter=2%28L%2BW%29\"$
\n" ); document.write( "But, $\"L=2W\"$ , twice as long as its width
\n" ); document.write( "So,
\n" ); document.write( " $\"P=2%282W%2BW%29\"$
\n" ); document.write( " $\"30ft=4W%2B2W\"$
\n" ); document.write( " $\"30ft=6W\"$ -----> $\"cross%2830%295ft%2Fcross%286%29=cross%286%29W%2Fcross%286%29\"$
\n" ); document.write( " $\"W=5ft\"$
\n" ); document.write( "And, $\"L=2%2A5=10ft\"$
\n" ); document.write( "Check,
\n" ); document.write( " $\"30ft=2%2810%2B5%29\"$
\n" ); document.write( " $\"30ft=2%2815%29\"$
\n" ); document.write( " $\"30ft=30ft\"$
\n" ); document.write( "Thank you,
