I want to know the answer to the following question:
Out of the 620.34 square miles, how much of it is water?
All the background I'm provided with is that "According to the United States Census Bureau, the city has a total area of 620.34 square miles (1,606.7 km2), of which, 601.11 square miles (1,556.9 km2) of it is land and 19.23 square miles (49.8 km2) of it is water.". Is that enough to answer the question?
