I want to know the answer to the following question:
What is the size in square miles today?
All the background I'm provided with is that "The rise in population of the surrounding districts helped lead to the Act of Consolidation of 1854, which extended the city limits of Philadelphia from the 2 square miles of present-day Center City to the roughly 130 square miles of Philadelphia County.". Is that enough to answer the question?
Answer: yes
