I want to know the answer to the following question:
What is the population of the London Metropolitan Region?
All the background I'm provided with is that "The extended area known as the London Metropolitan Region or the London Metropolitan Agglomeration, comprises a total area of 8,382 square kilometres (3,236 sq mi) has a population of 13,709,000 and a population density of 1,510 inhabitants per square kilometre (3,900/sq mi).". Is that enough to answer the question?
