# Similar Pentagon Areas Part 2

**Geometry**Level 2

Let a *pentasquish* be a pentagon with the following properties:

- Two non-adjacent right angles
- All sides congruent

If the area of a pentasquish is \( \left(a+\dfrac{\sqrt{b}}{c} \right)s^2\), where \(s\) is the length of one of the sides, and \(a\), \(b\), and \(c\) are positive integers with \(b\) square-free, find \(a+b+c\).
