Answer 2

Let the number of rows be x

We are given that the number of rows is equal to number of columns

So,

$x \times x = 500$

${x}^{2} = 500$

$x = \sqrt{500}$

$x = 22.36$

So, Number of rows = 22 = number of columns

So, Number of students in arrangement =- 22*22=484

No. of children would be left out in this arrangement = 500 - 484 = 16

Hence 16 children would be left out in this arrangement
