L=2W
\n" ); document.write( "2L+2W=126
\n" ); document.write( "2(2W)+2W=126
\n" ); document.write( "4W+2W=126
\n" ); document.write( "6W=126
\n" ); document.write( "W=21 METERS IS THE WIDTH.
\n" ); document.write( "L=2*21=42 METERS IS THE LENGTH.
\n" ); document.write( "PROOF:
\n" ); document.write( "2*42+2*21=126
\n" ); document.write( "84+42=126
\n" ); document.write( "126=126
\n" ); document.write( "
