Fibonacci Rectangle Paradox

The reason this paradox works out goes back to a law discovered by Kepler on the Fibonacci sequence.

“The square of any Fibonacci is equal to the product of the adjacent numbers in the sequence minus one”.

8 x 8 = 64 
(5 x 13) - 1 = 64


The reality is that behind the line of the main diagonal of the rectangle, there is a evasive parallelogram with an area of 1x1.
