Why are the states west of the Mississippi River more squared shaped than the states on the east of the Mississippi River?

Because the states west of the Mississippi River strike a better balance between business investment in these territories.

Explanation:

The states that make up the USA have straight borders and square shapes, since colonial times. This was done to facilitate the delimitation of the colonies as well as the inspection between them. The borders were not determined by natural barriers such as rivers, mountains, among others, which facilitated this more square format of the borders.

Around the Mississippi River, we can see that the states that settle farther west of the river are more square than those that lie east of the river. This is because the states to the west of the Mississipi River, sought to make their territories more similar, thus providing a balance between the investment of companies in this region.
