Answer:
[tex]A=256\ units^2[/tex]
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 :
[tex]A=\dfrac{1}{3}bH[/tex]
Where
b is the area of base
[tex]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[/tex]
So, the required area is equal to [tex]256\ units^2[/tex].
