Question

A slice is made parallel to the base of a right rectangular pyramid, as shown.

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

Answer 1

The answer to this question is the number 2

Answer 2

`2\ cm^(2)`

Explanation:

we know that

The area of the resulting two-dimensional cross-section is the area of a rectangle

The area of a rectangle is equal to

`A=bh`

we have

`b=1\ cm`

`h=2\ cm`

substitute

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