Taking the ratio 3:2
\n" ); document.write( "3x * 2x = 864
\n" ); document.write( "6x^2 = 864
\n" ); document.write( "x^2 = 144
\n" ); document.write( "x =\"sqrt%28144%29\"
\n" ); document.write( "x = 12
\n" ); document.write( "So, Length = 3* 12 = 36cm
\n" ); document.write( "Breadth = 2 * 12 = 24cm
\n" ); document.write( "36 * 24 = 864cm^2
\n" ); document.write( "Hope this helps.
