The road will be divided into four roads of 5km and 2 km long interconnected road.
Explanation:
- According to my knowledge, four cities should be neighboring cities if they had to be joined by a single road of 22 km.
- So they must be 5km apart from each other ar four different ends.
- If we assume that the cities are equally apart by 5km.
- Then these cities will have a road of 5km each and there will be an interconnected road of 2 km long that will connect all the four roads of 5km long.

Each city is 12 Km away from each other using the new road and the total length of road connecting all four is 24 Km.
Step-by-step explanation:
The question is incomplete. It should actually be four cities that are 8 KM apart. They need to be connected by a road of 22 Km. Please refer to the attached picture for the diagram.
From the figure, we find that ABCD is a square with each side 8 KM. In order to connect all four points A, B, C and D, we can connect roads as shows in the attached picture.
Each city is 12 Km away from each other and the total length of road connecting all four is 24 Km.
These roads will connect all four cities within the available budget.
