You’re wrong here. See the coastline paradox. Lines can be as long as they want, just by being extremely crinkly. There’s no law that says a shorter curve cannot enclose a longer one.
I am right here. Those small bays are not important in this case when we want to calculate the amount of water pouring out to sea. The mouth of the river Amazone is 200 km wide. Not as wide as the sum of all underwater bays and peninsulas.
Okay. So when I was calculating how many Amazons were needed the perimeter didn’t matter, and the answer was just 3. But when you asked how many litres would be pouring over each meter of perimeter I did the calculation based on the idea that an equal amount of water was passing over each bit of the perimeter.
Otherwise the answer is of course that the water forms together into rivers so that most of the perimeter has no water passing over it but the mouths of the rivers have a great deal of water passing over them.
