Question

The multiple connected zones of Hamilton are shown in a planar map, in the following Fig.1. Draw
the planar graph for the following map (in Fig. 1) of multiple connected zones. Find out the minimum number
of frequencies needs to be used using graph theory, so that different zones of the following planar map are
assigned with different frequencies (i.e., each zone operates at one single frequency) in such a way that no
adjacent zones (i.e., zones with common borders) use the same frequency? The frequencies available for use
are 10 GHz, 20 GHz, 40 GHz, 60 GHz, 80 GHz, 100 GHz, 120 GHz, and 140 Hz. Show your detailed work.
