width = x
\n" ); document.write( "length = 4x\r
\n" ); document.write( "\n" ); document.write( "perimeter = 2*(L+W)\r
\n" ); document.write( "\n" ); document.write( "200=2*(5x)
\n" ); document.write( "200=10x
\n" ); document.write( "/10
\n" ); document.write( "x=20\r
\n" ); document.write( "\n" ); document.write( "length = 20*4=80\r
\n" ); document.write( "\n" ); document.write( "width = 20
\n" ); document.write( "length = 80
\n" ); document.write( "
