Detailed explanation-1: -Under the terms of the treaty negotiated by Trist, Mexico ceded to the United States Upper California and New Mexico. This was known as the Mexican Cession and included present-day Arizona and New Mexico and parts of Utah, Nevada, and Colorado (see Article V of the treaty).

Detailed explanation-2: -The Mexican Cession (Spanish: Cesión mexicana) is the region in the modern-day southwestern United States that Mexico originally controlled, then ceded to the United States in the Treaty of Guadalupe Hidalgo in 1848 after the Mexican–American War.

Detailed explanation-3: -Mexican officials and Nicholas Trist, President Polk’s representative, began discussions for a peace treaty that August. On February 2, 1848 the Treaty was signed in Guadalupe Hidalgo, a city north of the capital where the Mexican government had fled as U.S. troops advanced.

Detailed explanation-4: -The Gadsden Purchase, or Treaty, was an agreement between the United States and Mexico, finalized in 1854, in which the United States agreed to pay Mexico $10 million for a 29, 670 square mile portion of Mexico that later became part of Arizona and New Mexico.

Detailed explanation-5: -How did once-dominant Mexico lose the Mexican-American War? Mexico was essentially broke. The country was racked by financial instability as the war began in 1846. America’s blockade of Mexican ports worsened an already difficult situation, as Mexico couldn’t import and export goods, or levy taxes on imports.
