Answer:
Area of the two dimensional cross section is option 5. 144
Step-by-step explanation:
As we can see in the picture attached the slice perpendicular to the base of a rectangular prism will look like as yellow rectangle in two dimensional cross section.
So the sides of the rectangle will be 12 units each.
and the area of the two dimensional cross section will be = side × side = side² = 12² = 144 unit²
Therefore the answer is 144.
