Question

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

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


15 cm²

18 cm²

25 cm²

50 cm²

Answer 1

15cm

Explanation:

Answer 2

The answer would be the first choice.
`15 cm^(2)`

Explanation: The reason for this is that the question was pretty much just asking what the area of the resulting two-dimensional cross section would be -the shape in gray- (which can be found by using the formula
`lw`. To add on, since the dimensions of the shape are already given (5 and 3) all you've to do is multiply: 3*5=15

That's how you get to the answer.
