Question

A right rectangular pyramid is sliced parallel to the base as shown.

What is the area of the resulting two-dimensional cross-section?

A. 2
B. 3
C. 9
D. 12

Answer 1

`A=2\ m^(2)`

Explanation:

we know that

The resulting two-dimensional cross-section is a rectangle 1 m x 2 m

so

the area of this rectangle is equal to

`A=2*1=2\ m^(2)`
