\n" ); document.write( "Perimeter of rectangular field is $\"P=2L%2B2W\"$ \r
\n" ); document.write( "\n" ); document.write( "if $\"P=%283%2F5%29km\"$ and it's length is twice its breadth, $\"L=2W\"$ , then we have\r
\n" ); document.write( "\n" ); document.write( " $\"%283%2F5%29km=2%2A2W%2B2W\"$ ..............convert $\"%283%2F5%29km\"$ in meters and solve for $\"W\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"%283%2F5%29km=%283%2F5%291000m=%283000%2F5%29m=600m\"$
\n" ); document.write( " $\"600m=4W%2B2W\"$
\n" ); document.write( " $\"600m=6W\"$
\n" ); document.write( " $\"600m%2F6=W\"$
\n" ); document.write( " $\"W=100m\"$ \r
\n" ); document.write( "\n" ); document.write( "find the length:\r
\n" ); document.write( "\n" ); document.write( " $\"L=2W\"$
\n" ); document.write( " $\"L=2%2A100m\"$
\n" ); document.write( " $\"L=200m\"$ \r
\n" ); document.write( "\n" ); document.write( "so, dimensions of the field: $\"200m\"$ by $\"100m\"$ \r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
