Noticeable increase of its territory and possibility of westward expansion.

Explanation:

Hello!

The purchase of Louisiana's territory was a commercial agreement between the US government, whose president was Thomas Jefferson and France, whose First Consul was Napoleon Bonaparte.

On April 30, 1803, the acquisition treaty was signed in the city of Paris, in which the purchase price was established at 15,000,000 US dollars.

Finally, on December 20, 1803, France left New Orleans.

The purchase of Louisiana not only allowed the US to increase its territory, but also allowed it to expand westward, then accessing the Pacific Ocean.
