Question

A right rectangular pyramid is sliced parallel to the base, as shown. (100 POINTS)

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


2 m²

3 m²

9 m²

12 m²

Answer 1

That shaded region area we need

• length=2m
• Breadth=1m

Area

• Length×Breadth
• 2(1)
• 2m²

Answer 2

Answer: A) 2 m^2

Explanation:

We know, the 2-dimensional cross-section is a Rectangle.

Length (l) = 2 m
Breadth (b) = 1 m

Area of the Cross Section = l * b

Therefore,
= lb
= l * b
= 2 * 1
=> 2

Area of the Cross Section = 2 m^2
