Answer:

The area of the cross section is 2 cm^2.

Explanation:

If I am understanding your problem correctly, we are just looking for the area of the grey rectangle, which is the cross-section.

The length and width of this gray rectangle are already given to us. They are 1 and 2. Just multiply them to get the area.

1 x 2 = 2 cm^2
