Hi there,
\n" ); document.write( "Area = length x breadth
\n" ); document.write( "Area = 52.6 x 35.4
\n" ); document.write( "= 1862.04 m^2
\n" ); document.write( "1862.04 m^2 x 3.5
\n" ); document.write( "= rs 6517.14.
\n" ); document.write( "...............
\n" ); document.write( "Perimeter = 2 x Length + 2 x breadth
\n" ); document.write( "Perimeter = 2(52.6) + 2(35.4)
\n" ); document.write( "Perimeter = 176 m
\n" ); document.write( "Twice round = 352 m
\n" ); document.write( "352/2 = 176 seconds
\n" ); document.write( "176 seconds = 2 minutes 56 seconds.
\n" ); document.write( "Hope this helps :-)
\n" ); document.write( "
\n" );
