There are 2401 students in a school. The PT teacher wants all of them to stand in rows and columns. Find the number of rows, if the number of rows is equal to the number of columns.

Correct option is C

Given:

There are 2401 students in the school, and the number of rows is equal to the number of columns.

Formula Used:

Number of students = Number of rows × Number of columns.

Since the number of rows is equal to the number of columns, the number of rows is the square root of the total number of students.

Solution:

Number of row = $$\sqrt{2401} = 49$$​​

Therefore, the number of rows (and columns) is 49.
