Summary:
A common distribution of areas (or mass) is observed in fragments of glass, city roads, and cracking patterns. In order to study a generation mechanism of the scaling law, we consider a fractal-like hierarchical network construction based on random divisions of rectangles. The stochastic process makes a Markov chain and corresponds to directional random walks with splitting into four particles. We derive a combinatorial analytical form and its continuous approximation for the distribution of rectangle areas, and show a good fitting with the actual distribution in the averaging behavior of the divisions.
