Ling sees that in this window design there are rectangles of different sizes how many rectangles in all are in the design

I think it has 16 rectangles.

The window design has 6 small rectangles. 3 rectangles on top to the other 3.

      1          2           3
      4          5            6

1 = 1 big rectangle that encompasses the whole 6 small rectangle
6 = 6 small rectangles
2 = rectangles formed by 1-2-3 and 4-5-6
3 = rectangles formed by 1-4, 2-5, and 3-6
4 = rectangles formed by 1-2, 2-3, 4-5, 5-6

Ican’t answer if there is no diagram

The answer is 26 to 1
