We first find A2, for which we multiply A with itself. We perform matrix multiplication in which we multiply rows of first matrix with columns of second matrix element by element and add.
Answer: a) 
Step-by-step explanation:
We know that the volume of an oblique pyramid is given by :-

If the volume of an oblique pyramid with a square base is V units³ and the height is h units.
Then, we have

Multiply 3 on both sides , we get

Divide both sides by h , we get

i.e. 
Hence, the expression represents the area of the base of the pyramid = 
Hence, the correct answer is a) 3 v/h units^2
