Answer 2

Students in each rows is 90.

Step-by-step explanation:

Given:

students are arranged in rows to make  a perfect square.

60 students are left out If the no of students  was 8160.

To Find:

Students in each rows.

Formula Used:

To arrange  a square  the number of rows and the number of columns should  equal.

Solution:

As given -60 students are left out If the no of students  was 8160.

Total number of student available =8160- 60

                                                        = 8100  

Let the side of square is P.

Total number of students $=PXP=P^{2}$

Hence $P^{2}=8100$

           $P=\sqrt{8100}$

           P=90

Thus, Students in each rows is 90.
