Options

A. 37
B. 33
C. 63
D. 47

Answer

To solve the problem of arranging 1369 students in equal rows and columns, we need to find the number of students in the last row, which will be the same as the number of students in each row.

### Step-by-Step Solution:

1. **Understand the Problem**: We need to arrange 1369 students in a square formation, meaning the number of rows will equal the number of columns.

2. **Identify the Mathematical Operation**: Since we want equal rows and columns, we need to find the square root of the total number of students.

3. **Calculate the Square Root**:
\[ \sqrt{1369} \]

4. **Perform the Calculation**:
- To find the square root of 1369, we can either use a calculator or perform the long division method for square roots.
- The square root of 1369 is 37.

5. **Conclusion**: Since the number of rows and columns is equal, and both are 37, the number of students in the last row is also 37.

### Final Answer:
The number of students in the last row is **37**.
