A man in Damascus offers to sell you three basket of herbs for one copper coin. Is this a good trade or a bad trade?

answer; i believe the correct answer is (clockwise and outward) about the center;

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
