Step-by-step explanation:

![\left[\begin{array}{ccc}-1&2&1\\1&-4&1\\-2&-2&1\end{array}\right]](https://tex.z-dn.net/?f=%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D-1%262%261%5C%5C1%26-4%261%5C%5C-2%26-2%261%5Cend%7Barray%7D%5Cright%5D%20%20)
Find the determinant
D = [(-1).(-4).1 + 2.1.(-2) + 1.1.(-2)] - [1.(-4).(-2) + (-1).1.(-2) + 2.1.1]
D = [4 - 4 - 2] - [8 + 2 + 2]
D = -10 - 12
D = -22
A = |D|/2
A = |-22|/2
A = 22/2
A = 11
