What is the largest city in the world by area?

Unlike measuring population, determining the largest city in the world by area is a less straight-forward exercise. Each country has its own definition of what constitutes a city, making a standard measurement for the largest city by area harder to determine. For example, the World Population Review says the city of Sermersooq in Greenland is, by their standard of measurement for a city, over 205,400 square miles for a population of 23,123 people.
