Fibo's quickie (Posted on 2014-09-03)

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.

Solution: (Hide)

Validate or disprove?

Disprove:

1. No three distinct Fibo numbers satisfy a+b>c.
2. All values like ab/c are proportional to length and cannot represent an area.

Each of the above reasos is sufficient.
