Question

a school has 700 student. for a p.t drill formation students have to stand in straight lines with equal number of rows and column. how many children's are left out in such a formation?​

Answer 1

Answer:

24 students are left out

Step-by-step explanation:

Let the number of rows/columns = x

Hence, we need to find a square number closest to 700.

$20^{2} = 400\\30^{2} = 900$

which means the number is between 20 and 30.

$25^{2} = 625\\27^{2} = 729$

Which means the number is between 25 and 27, which means it is 26.

$26^{2} = 676\\700 - 676 = 24$

Hence, 24 students are left.
