Answer
The total weight of the Hamilton circuit is 82.
Work Step by Step
To find the total weight of the Hamilton circuit, we can simply add up the weight of each edge in the circuit.
The Hamilton circuit is A,C,D,B,A. So the edges that are used in the Hamilton circuit are AC, CD, DB, and BA.
The weights of these five edges are 20, 10, 12, and 40.
total weight = 20 + 10 + 12 + 40
total weight = 82
The total weight of the Hamilton circuit is 82.
