length= 42\r
\n" ); document.write( "\n" ); document.write( "width=0\r
\n" ); document.write( "\n" ); document.write( "2(42)+2(0)=84\r
\n" ); document.write( "\n" ); document.write( "84=perimeter\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "width is 0 so perimeter is 84 more than width
\n" ); document.write( "
