3. 3

   Forward conversion

   $$\begin{array}{rl}1\mathrm{ha}& =\frac{10,000\cancel{m2}}{1,000,000\cancel{m2}}\times 1km2\\ & =\frac{10,000}{1,000,000}km2\\ & =0.01km2\end{array}$$
4. 4

   Reverse conversion

   $$\begin{array}{rl}1km2& =\frac{1,000,000\cancel{m2}}{10,000\cancel{m2}}\times 1\mathrm{ha}\\ & =\frac{1,000,000}{10,000}\mathrm{ha}\\ & =100\mathrm{ha}\end{array}$$
