I want to know the answer to the following question:
When was the last time the area of Bern was measured?
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
