?+(4+?)+(6+?)−(6+8+12)=2sh  ⇒3?−16=2sh  (4+?)−8=(s/2)(2h)=sh⇒sh=?−4  ⇒2sh=3?−16=2?−8⇒?=8  ⇒Area of hexagon=6+8+12+8+(4+8)+(6+8)  =60
$$?+\left(\mathrm{4}+?\right)+\left(\mathrm{6}+?\right)−\left(\mathrm{6}+\mathrm{8}+\mathrm{12}\right)=\mathrm{2sh} \\ $$$$\Rightarrow\mathrm{3}?−\mathrm{16}=\mathrm{2sh} \\ $$$$\left(\mathrm{4}+?\right)−\mathrm{8}=\frac{\mathrm{s}}{\mathrm{2}}\left(\mathrm{2h}\right)=\mathrm{sh}\Rightarrow\mathrm{sh}=?−\mathrm{4} \\ $$$$\Rightarrow\mathrm{2sh}=\mathrm{3}?−\mathrm{16}=\mathrm{2}?−\mathrm{8}\Rightarrow?=\mathrm{8} \\ $$$$\Rightarrow\mathrm{Area}\:\mathrm{of}\:\mathrm{hexagon}=\mathrm{6}+\mathrm{8}+\mathrm{12}+\mathrm{8}+\left(\mathrm{4}+\mathrm{8}\right)+\left(\mathrm{6}+\mathrm{8}\right) \\ $$$$=\mathrm{60} \\ $$

ΔABC=6+12−8=10  hexagon′s area =6×ΔABC=60
$$\Delta{ABC}=\mathrm{6}+\mathrm{12}−\mathrm{8}=\mathrm{10} \\ $$$${hexagon}'{s}\:{area}\:=\mathrm{6}×\Delta{ABC}=\mathrm{60} \\ $$
