Answer:

By constructing two diagonal roads. [tex]l \approx 22.627\,km[/tex]

Step-by-step explanation:

The only feasible solution is the construction of two diagonal roads between each pair of cities. The total length is:

[tex]l = 2\cdot \sqrt{2}\cdot (8\,km)[/tex]

[tex]l \approx 22.627\,km[/tex]
