Area=l*b
\n" ); document.write( "perimeter=2(l+b)
\n" ); document.write( "l*b=2 --eq-1
\n" ); document.write( "2(l+b)=6 --eq-2
\n" ); document.write( "In equation no-1
\n" ); document.write( "l*b=2
\n" ); document.write( "l=2/b
\n" ); document.write( "Substitute this value into equation no-2
\n" ); document.write( "2(l+b)=6
\n" ); document.write( "After Substituting l=2/b
\n" ); document.write( "2(2/b+b)=6
\n" ); document.write( "2\"%282%2Bb%5E2%2Fb%29\"=6
\n" ); document.write( "\"4%2B2b%5E2%2Fb\"=6
\n" ); document.write( "4+\"2b%5E2\"=6b
