On a Mercator projection map, Greenland looks larger than South America. However, it is actually much smaller. How could this affect a person's understanding of land areas?

answer(c) carved on a babylonian clay tablet that showed earth as a flat circular disk;

the answer would be the third option, "no, ariel should have added 9^2 and 12^2 and compared that to 15^2."

this is found through the pythagorean theorem, which is a^2 + b^2 = c^2.

this is the correct way of solving the problem:

9^2 + 12^2 = 15^2

81 + 144 = 225

225 = 225
