$$1050\times {2\mathrm{dm}}^2={2100\mathrm{dm}}^2={21\mathrm{m}}^2$$

$$\mathrm{square}1s_1=12\mathrm{m}\Rightarrow {\mathrm{area}}_1={144\mathrm{m}}^2$$$$\mathrm{square}2s_2=5\mathrm{m}\Rightarrow {\mathrm{area}}_2={25\mathrm{m}}^2$$$$\mathrm{square}3{\mathrm{area}}_3={144\mathrm{m}}^2+{25\mathrm{m}}^2={169\mathrm{m}}^2\Rightarrow$$$$\Rightarrow s_3=\sqrt{{169\mathrm{m}}^2}=13\mathrm{m}$$
