Now given that

No of children present at assembly :- 3131
No of children joined the assembly :- 5
Now
total number of students = 3136
also it's given number of childrens in a row = no of rows

then let the number of
row = X = no. of children in a row

then

X × X = 3136

=> $X^2$ = 3136

$= > \sqrt{ {X}^{2} } = \sqrt{3136} \\ \\ = > X = 56$
then number of rows = 56
