Answer 2

$\it \mathcal{A}_{AMD}=\dfrac{AD\cdot d(M,\ AD)}{2}=\dfrac{\mathcal{A}_{ABCD}}{2}\ \ \ \ \ (1)\\ \\ \\ \mathcal{A}_{BCD}=\dfrac{BC\cdot d(D,\ BC)}{2}=\dfrac{\mathcal{A}_{ABCD}}{2}\ \ \ \ \ (2)\\ \\ \\ (1),\ (2) \Rightarrow \mathcal{A}_{AMD}=\mathcal{A}_{BCD} \Rightarrow \mathcal{A}_{AMD}-\mathcal{A}_{EMD}=\mathcal{A}_{BCD}-\mathcal{A}_{EMD} \Rightarrow\\ \\ \\ \Rightarrow \mathcal{A}_{AED}=\mathcal{A}_{DCM}+\mathcal{A}_{EMB}$
