$$\mathrm{square}\:\mathrm{1}\:{s}_{\mathrm{1}} =\mathrm{12m}\:\Rightarrow\:\mathrm{area}_{\mathrm{1}} =\mathrm{144m}^{\mathrm{2}} \\ $$$$\mathrm{square}\:\mathrm{2}\:{s}_{\mathrm{2}} =\mathrm{5m}\:\Rightarrow\:\mathrm{area}_{\mathrm{2}} =\mathrm{25m}^{\mathrm{2}} \\ $$$$\mathrm{square}\:\mathrm{3}\:\mathrm{area}_{\mathrm{3}} =\mathrm{144m}^{\mathrm{2}} +\mathrm{25m}^{\mathrm{2}} =\mathrm{169m}^{\mathrm{2}} \:\Rightarrow \\ $$$$\Rightarrow\:{s}_{\mathrm{3}} =\sqrt{\mathrm{169m}^{\mathrm{2}} }=\mathrm{13m} \\ $$
