I don't understand???

Im confused??

Part A: Rectangle

Part B: Rectangle

Step-by-step explanation:

We are given a rectangular prism as shown.

Part A: After slicing the rectangular prism with a plane parallel to the base, we see that the cross-sectional region will be similar to a rectangle.

Thus, the cross-sectional region is a RECTANGLE.

Part B: After slicing the rectangular prism with a plane perpendicular to the base, we see that the cross-sectional region will be similar to a rectangle.

Thus, the cross-sectional region is again a RECTANGLE.

Hence, for both the parts, the cross sectional plane is a Rectangle.
