I want to know the answer to the following question:
What is 33.6% of the land in Bern?
All the background I'm provided with is that "Of the rest of the land, 23.25 square kilometers (8.98 sq mi) or 45.0% is settled (buildings or roads), 1.06 square kilometers (0.41 sq mi) or 2.1% is either rivers or lakes and 0.16 square kilometers (0.062 sq mi) or 0.3% is unproductive land.". Is that enough to answer the question?
Answer: no
