The figure may be labelled as shown.
The pentagons in the figure, are ABDFH, CDFHB, EFHBD, GHBDF, ACDFG, CEFHA, EGHBC, GABDE, BDEGH, DFGAB, FHACD and HBCEF. Clearly, these are 12 in number.

A pentagon should be connected start to end. Not open, just because it has 5 points it does not mean it's a pentagon. Like abdfh, cdfhb. That is a pentagon!

I can't understand this concept. How can we take this (HBCEF) as pentagon? Please explain.

This is wrong. There are 16. It's forgotten to count ABDFH, BCDFH, BDEFH, and BDFGH.
Correct me, if I am wrong.
