Fibonacci question

lets say i have a abcd pattern

the line bc is at 0.618 retracement of line ab.

and cd is at 1.272 extension of line ab drawn down to bc.

does that mean that cd is 1.272 times longer than line ab?

or what does it mean

The vertical distance of AD is larger than the vertical distance of AB by 1.272 times. So AB =1 and AD =1.272
