I want to know the answer to the following question:
What is the approximate area of the core of the City of London?
All the background I'm provided with is that "London's ancient core, the City of London, largely retains its 1.12-square-mile (2.9 km2) medieval boundaries and in 2011 had a resident population of 7,375, making it the smallest city in England.". Is that enough to answer the question?
Answer: yes
