\n" );
document.write( "Let width be W
\n" );
document.write( "Then length = 2W
\n" );
document.write( "Since perimeter = 120 cm, then: 2W + 2(2W) = 120
\n" );
document.write( "2W + 4W = 120
\n" );
document.write( "6W = 120
\n" );
document.write( "W, or width = , or 
\n" );
document.write( "Length = 2(20), or  \n" );
document.write( "

\n" );
