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

   Rewrite acre in the base unit

   $$1\mathrm{acre}=4,046.86{\mathrm{m}}^2$$
3. 3

   Forward conversion

   $$\begin{array}{rl}1\mathrm{f}{\mathrm{t}}^2& =\frac{0.092903\cancel{{\mathrm{m}}^2}}{4,046.86\cancel{{\mathrm{m}}^2}}\times 1\mathrm{acre}\\ & =\frac{0.092903}{4,046.86}\mathrm{acre}\\ & =0.000022956811\mathrm{acre}\end{array}$$
4. 4

   Reverse conversion

   $$\begin{array}{rl}1\mathrm{acre}& =\frac{4,046.86\cancel{{\mathrm{m}}^2}}{0.092903\cancel{{\mathrm{m}}^2}}\times 1\mathrm{f}{\mathrm{t}}^2\\ & =\frac{4,046.86}{0.092903}\mathrm{f}{\mathrm{t}}^2\\ & =43,560.057264\mathrm{f}{\mathrm{t}}^2\end{array}$$
