Question
Choose the correct answer from the given four options.The matrix $\text{P}=\begin{bmatrix}0&0&4\\0&4&0\\4&0&0\end{bmatrix}$ is a:
  1. Square matrix.
  2. Diagonal matrix.
  3. Unit matrix.
  4. None of these.
✓

Answer

  1. Square matrix.
Solution:
We know that, in a square matrix number of rows are equal to the number of columns.
So, the matrix $\text{P}=\begin{bmatrix}0&0&4\\0&4&0\\4&0&0\end{bmatrix}$ is a square matrix.
