Arranging Children in Rows and Columns
Given: 500 children
Objective: To arrange them in such a manner that the number of rows is equal to the number of columns.
Finding the square root of 500
To arrange the children in rows and columns, we need to find the square root of 500. The square root of 500 is approximately 22.36. However, we cannot have a decimal number of rows or columns, so we need to round down to the nearest whole number.
Therefore, the maximum number of rows and columns we can have is 22.
Finding the Number of Children Left Out
To find the number of children left out, we need to subtract the number of children in the arranged rows and columns from the total number of children.
The number of children in the arranged rows and columns is 22 x 22 = 484.
Therefore, the number of children left out is 500 - 484 = 16.
Conclusion
In conclusion, to arrange 500 children in rows and columns where the number of rows is equal to the number of columns, we can have a maximum of 22 rows and 22 columns. This would leave 16 children left out of the arrangement.
