Answer 1

Answer:

$A=256\ units^2$

Step-by-step explanation:

The given figure shows a triangular pyramid having 16 units as height. The base of pyramid is triangle.

The area of a triangular pyramid is given by :

$A=\dfrac{1}{3}bH$

Where

b is the area of base

$A=\dfrac{1}{3}\times \dfrac{1}{2}\times B\times h\times H\\\\=\dfrac{1}{6}\times 12\times 8\times 16\\\\=256\ units^2$

So, the required area is equal to $256\ units^2$.
