The test suite checks for equality, but different techniques have small numerical differences. The test suite should allow for these differences, as it eliminates many solutions that are correct.

This problem has been updated to check against a small error value rather than for equality.

Hi Team,

I am getting error after submitting as,

"We're sorry, but something went wrong. We've been notified about this issue and we'll take a look at it shortly"

Thanks and Have a Good DaY

Would the use of polyarea(x,y) work?
I tried but I'm getting an issue to submit!
