The correct Answer is:
To determine the number of rows in the given matrix `[(3,4,5),(6,7,8),(9,10,11)]`, we can follow these steps: 1. **Identify the Matrix**: The matrix is given as `[(3,4,5),(6,7,8),(9,10,11)]`. This is a collection of ordered pairs (or tuples) arranged in a rectangular format. 2. **Understand Rows and Columns**: In a matrix, rows are the horizontal lines of elements, while columns are the vertical lines. 3. **Count the Rows**: - The first row is `(3, 4, 5)`. - The second row is `(6, 7, 8)`. - The third row is `(9, 10, 11)`. By counting these, we can see there are 3 rows in total. 4. **Conclusion**: Therefore, the number of rows in the matrix is **3**. Final Answer: The number of rows of the matrix is **3**.
