Consider a square of side length $13$.
Let it be divided into:
- a $13 \times 5$ rectangle, divided into two right triangles by its diagonal
- a $13 \times 8$ rectangle, divided into trapezia with side lengths $8$ and $5$:
Let the pieces be rearranged to form two long right triangles arranged to form a $21 \times 8$ rectangle.
The area of the square is $13 \times 13 = 169$.
