- Having completed the necessary measurements to find the areas of gray rectangular triangles and squares.
- fold all the areas of the calculated gray figures at the previous stage (step 5).
- Subtract from the area rectangle (step 3) of the area of gray figures (step 6). The result is the desired area.
