The line has 0 height and ∞ lenght so the area is 0*∞=0 but it is made from ∞ points with 0 length so 0*∞=∞.

What's your opinion about this?

hi popotamian

Welcome to the forum.

Mathematicians have a symbol for infinity and use it in certain topics but have found it is best not to regard it as a number, as it doesn't obey the usual rules. Your question is a good demonstration of this. Here's some more:

∞ +1 = ∞

∞ x 5 = ∞

∞ x 7 = ∞

∞ /∞ = ????

Specifically, the ubiquitous operations are not defined for infinity.
