\n" ); document.write( "let x=width of rectangle
\n" ); document.write( "3x=length of rectangle
\n" ); document.write( "2(width+length=perimeter
\n" ); document.write( "2(x+3x)=72
\n" ); document.write( "8x=72
\n" ); document.write( "x=9
\n" ); document.write( "3x=27
\n" ); document.write( "width of rectangle=9 in
\n" ); document.write( "3x=length of rectangle=27 in \n" ); document.write( "

\n" );
