I want to know the answer to the following question:
How many square feet of office space did Houston have in Uptown in 2002?
All the background I'm provided with is that "In 2002, Uptown had more than 23 million square feet (2,100,000 m²) of office space with 16 million square feet (1,500,000 m²) of Class A office space.". Is that enough to answer the question?
Answer: yes
