1. 1

   Rewrite ha in the base unit

   $$1\mathrm{ha}=10,000{\mathrm{m}}^2$$
2. 2

   Rewrite ft² in the base unit

   $$1\mathrm{f}{\mathrm{t}}^2=0.092903{\mathrm{m}}^2$$
3. 3

   Forward conversion

   $$\begin{array}{rl}1\mathrm{ha}& =\frac{10,000\cancel{{\mathrm{m}}^2}}{0.092903\cancel{{\mathrm{m}}^2}}\times 1\mathrm{f}{\mathrm{t}}^2\\ & =\frac{10,000}{0.092903}\mathrm{f}{\mathrm{t}}^2\\ & =107,639.150512\mathrm{f}{\mathrm{t}}^2\end{array}$$
4. 4

   Reverse conversion

   $$\begin{array}{rl}1\mathrm{f}{\mathrm{t}}^2& =\frac{0.092903\cancel{{\mathrm{m}}^2}}{10,000\cancel{{\mathrm{m}}^2}}\times 1\mathrm{ha}\\ & =\frac{0.092903}{10,000}\mathrm{ha}\\ & =0.0000092903\mathrm{ha}\end{array}$$
