Find the order of the matrix .
`[(7,4,6,1),(20,0,1,7),(6,1,14,4)] `

Answer

To find the order of the given matrix, we follow these steps:

### Step-by-Step Solution:

1. **Identify the Matrix**: The given matrix is
\[ \begin{bmatrix} 7 & 4 & 6 & 1 \\ 20 & 0 & 1 & 7 \\ 6 & 1 & 14 & 4 \end{bmatrix} \]

2. **Count the Rows**:
- A row is a horizontal line of elements in the matrix.
- In the given matrix, we can see that there are 3 horizontal lines (rows):
- Row 1: (7, 4, 6, 1)
- Row 2: (20, 0, 1, 7)
- Row 3: (6, 1, 14, 4)
- Therefore, the number of rows is **3**.

3. **Count the Columns**:
- A column is a vertical line of elements in the matrix.
- In the given matrix, we can see that there are 4 vertical lines (columns):
- Column 1: (7, 20, 6)
- Column 2: (4, 0, 1)
- Column 3: (6, 1, 14)
- Column 4: (1, 7, 4)
- Therefore, the number of columns is **4**.

4. **Write the Order of the Matrix**:
- The order of a matrix is expressed in the format "number of rows × number of columns".
- Since we have 3 rows and 4 columns, the order of the matrix is written as:
\[ 3 \times 4 \]

### Final Answer:
The order of the matrix is **3 × 4**.
