You have 20 seconds (starting at the end of reading the puzzle)
to validate or to disprove the following formula of calculating
the area of a triangle:

S=1/3* ((2AB/C)+(2AC/B)+(2BC/A)).

where the sides A,B & C are represented by three different Fibonacci numbers.

This can't possible work because of the triangle inequality.  No 3 different Fibonacci numbers can possibly be the sides of a triangle.

3 consecutive Fibonacci numbers will satisfy A+B=C thereby being collinear.  This 'triangle' would have zero area. The formula given always has a positive result.

Did you just make the formula up?
