# Area after folding

**Geometry**Level 4

\(AB\) and \(CD\) are then folded along \(AP\) and \(QC\) respectively to form \(AB'\) and \(CD'\) respectively. Similarly, \(BP\) and \(QD\) are folded along \(AP\) and \(QC\) respectively to form \(PB'\) and \(QD'\).

It is known that \(AB'CD'\) is a rhombus, find the area of \(AB'CD'\).
