\$\begingroup\$ Rounding was just a red herring because twice the area is always exactly integer. \$\endgroup\$

\$\begingroup\$ @VladimirReshetnikov Out of curiosity: if you knew rounding was a red herring, then why add it to distract from the otherwise good challenge?.. Not all languages have builtin Banker's rounding, not even well-known languages like JS and Java apparently. I like the challenge in general and enjoyed writing my Java answer, but the rounding and lack of explanation what Convex Hull is to make the challenge self-contained refrained me from upvoting it, tbh.. PS: Sorry @Arnauld to do this as a comment in your answer.. \$\endgroup\$
