These are in fact 3 series based on the 3 polyores of area

At the end of this series, for = 3, we have an area of 36φ + 27 ; in the series of regular pentagons, for = 3φ, we also have an area of 36φ + 27.

Is it possible to find a set of polyores whose total area is 36φ + 27 and which covers both the trapezoid and the pentagon ?

I dedicate this series to Robin King who found solutions to the first 39 trapezoids of this series ; she did not find a solution to the 40th ; neither do I and I don't know if there is a solution..

This series is copied from the previous series with sides of length
φ + 1 but the trapezoids are replaced by parallelograms.

I called it "Series of Robin King's parallelograms" because I think she would have liked this challenge. If someone gives me the solutions of the 40 parallelograms, then I would extend the list.
