Answer: 51
Step-by-step explanation:
From the question, we are informed that there are 2601 students in a school and that the teacher want them to stand in rows and columns.
Since the number of the row and column are equal, thus will go thus:
Let the number of row and column be represented by y. Therefore,
y × y = 2601
y² = 2601
y = ✓2601
y = 51
Therefore the rows and columns must be 51 each.
