Step-by-step explanation:
The war between Mexico and the United States of America, also known as the First American Intervention in Mexico, which took place between 1846 and 1848, had as a consequence for Mexico the loss of approximately 2,378,540 square km of territory, and for the United States the annex of these lands.
