We have a group of 169 students that needs to be seated in a square formation. Then, the number of rows has to be the square root of 169 :-
Then, a square of 13 rows and 13 columns will fit the 169 students.
If the number of students is 1024, then the number of rows <em>N </em>can be calculated as :-
169 students will seat in a 13×13 formation.
1024 students will seat in a 32×32 formation (N=32)
