Kata

Don't mark unsolved issues as solved:

• Result should be handled by using approximate equality instead of rounding
• Spare us the input validation. This is documented.
• If you don't check, possibly by testing intermediate results, that solvers use a particular method, the description should not positively say "using the shoelace formula". You can describe possible methods, but kata generally test results, not methods.

• Calculating the area of a triangle is not Hard. It is not a 5kyu task ( that problem will solve itself ), and it should not be described in the kata title as hard, which raises expectations that are bound to be disappointed, and does not fit with other problems on the site. Optimal Transportation is Hard. Transpiling to BF is Hard. Area'ing a triangle is not.

• Random inputs are not actually random
• Result should be handled by using approximate equality instead of rounding
