let the width =x
\n" ); document.write( "so the length=3x
\n" ); document.write( "so the perimeter= 2(x+3x)=8x=168 given
\n" ); document.write( "so x=168/8=21 is width
\n" ); document.write( "so the length=63
\n" ); document.write( "ans\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
\n" );
