I want to know the answer to the following question:
How many square miles of territory were added to the British Empire between 1815 and 1914?
All the background I'm provided with is that "Between 1815 and 1914, a period referred to as Britain's "imperial century" by some historians, around 10,000,000 square miles (26,000,000 km2) of territory and roughly 400 million people were added to the British Empire.". Is that enough to answer the question?
