Answer:
16 children would be left out in this arrangement
Step-by-step explanation:
Total number of children in a school = 500
For P.T. Drill number of rows = number of columns =x
The number of children who will be left out = 500−x^2 .
The square root of 500 gives remainder as 16 that means, the square of 22 is less than 500 by 16
To make it a perfect square = 500−16=484 Therefore, number of children left will be 16
= 16 children would be left out in this arrangement
