Try to identify the pattern, and see the shapes not only as how it is given, but play around with them to identify their relationships, and this case, the shaded triangle is actually half of the two rectangles there. If you just flip one half of the symmetrical triangle up, you can see it nicely fits that one rectangle. So 1 unit is effectively 52 cm2, and that’s how you work through :)
