If the matrix is of 2 by 2 then we can find the determinant of the matrix.
Then (ad - bc ) gives you the determinant of the matrix.
For example,
= (2)(-2) - (1)(4)
= - 4 - 4
= -8
So, when finding the volume, we would just add up every side, and from the question above, it look like that the numbers that we would be adding are the following above.
The volume would be 11.2
The volume would be 11.2
