Looking at the whole trapezoid first, we can know that the height of the triangle in the shadow part and the blank part is the same. Although the shadow part is composed of two parts, it can be abstracted as a part, so the area ratio of the blank part and the shadow part is 10: 16, that is, 5: 8, and the area of the blank part can be 6 times 8 divided by 2=24, so the area of the shadow part is 24 times 8 divided by 5 = 34.
