Question

How did the United States acquired the Louisiana territory

Answer 1

ANSWER-
The United States purchased the Louisiana purchase for 15 million dollars. The U.S. added some 13 states worth of territories at less than three cents per acre.

Answer 2

The Americans thought that Napoleon might withdraw the offer at any time, preventing the United States from acquiring New Orleans, so they agreed and signed the Louisiana Purchase Treaty on April 30, 1803. Acquiring the territory doubled the size of the United States, at a sum of less than 3 cents per acre.
