I want to know the answer to the following question:
How many kilometers was Qing China at its height?
All the background I'm provided with is that "Qing China reached its largest extent during the 18th century, when it ruled China proper (eighteen provinces) as well as the areas of present-day Northeast China, Inner Mongolia, Outer Mongolia, Xinjiang and Tibet, at approximately 13 million km2 in size.". Is that enough to answer the question?
Answer: yes
