   $$1m2=1m2$$
3. 3

   Forward conversion

   $$\begin{array}{rl}1cm2& =\frac{0.0001\cancel{m2}}{1\cancel{m2}}\times 1m2\\ & =\frac{0.0001}{1}m2\\ & =0.0001m2\end{array}$$
4. 4

   Reverse conversion

   $$\begin{array}{rl}1m2& =\frac{1\cancel{m2}}{0.0001\cancel{m2}}\times 1cm2\\ & =\frac{1}{0.0001}cm2\\ & =10,000cm2\end{array}$$
