I’m studying Andrei Alexandrov’s Methods of the Qualitative Theory of Metric Spaces. If $E$ is a set in $\mathbb R^n$ (a closed, open or half-open subset), then it defines the set $d(E,\_)$ of points of $\mathbb R^n$ which are closer to $E$ than to $\mathbb R^n\setminus E$. This is the infimum of all $d(E,x)$ with $x\in\mathbb R^n\setminus E$. Now if $S$ is a subset of $\mathbb R^n$, we define its area as $$\operatorname{area}(S)=\iint_{\operatorname{graph}(d(S,\_))}1\;\mathrm dt\;\mathrm dx.$$ Then he says that “if $E_1$ and $E_2$ have a non empty intersection, then the areas of their boundary components coincide”. In other words: if $E_1$ and $E_2$ have non empty intersection, there is $E$ such that $\partial E_1=\partial E=\partial E_2$ and $\operatorname{area}(\partial E_1)=\operatorname{area}(\partial E_2)$. Why? Can you explain me? A: The fact is that \$\Delta=\{(
