suchmanner that the number of rows is equal to the number of columns.
How many children would be left in thus arrengment​

Answer 1

Answer:

484 and 16 will be left out

Step-by-step explanation:

As the number of rows is equal to the number of columns,

we can take a square root of the total number of children.

If we take the square root of 500, we have a remainder 16.

It means 484 children can be arranged in 22 rows and 22 columns and rest 16 will be left out

Answer 2

Let number of children in row and column be x.
Then number of children in row and column is x^2.
Now find the square root of 500 and remainder is the number of students.
So 16 students left over.
