I want to know the answer to the following question:
What is the current area of Mexico City?
All the background I'm provided with is that "In 1854 president Antonio López de Santa Anna enlarged the area of the Federal District almost eightfold from the original 220 to 1,700 km2 (80 to 660 sq mi), annexing the rural and mountainous areas to secure the strategic mountain passes to the south and southwest to protect the city in event of a foreign invasion.". Is that enough to answer the question?
Answer: no
