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 m²

b.) 3 m²

c.) 9 m²

d.) 12 m²

Option A.

Step-by-step explanation:

we know that

The resulting two-dimensional cross-section is a rectangle

The area of rectangle is equal to

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
