Question

There are 2121 students in a school. A PE teacher wants to arrange maximum possible number of students in the field such that the number of rows is equal to the number of columns. How many students are left out in this arrangement?

Answer 1

Step-by-step explanation:

If no. of students is 121,

So, if no. of rows and column are equal then, it is a square

So, side²= 121

side=11

Rows= 11

Columns= 11

So, Plz mark me as the brainliest

Answer 2

$\tt\blue{Given:-}$

$\small\tt{No. \: of \: rows = No. \: of \: columns}$

$\small\tt{No. \: of \: Students = 2121 \: students}$

$\: \: \: \: \: \: \: \: \: \: \: \: \:$

$\tt\blue{Solution:-}$

$\begin{array}{r|l|}4 \: \: & \: \: \: \: 2121&46 \: \\ + 4 \: \: &- 16 \: \: \: \\ 86& \: \: \: \: \: \: 521 \\ \: \: & \: \: - 516 \\& \: \: \: \: \: \: \: \: \: \: 5\end{array}$

$\: \: \: \: \: \: \: \: \: \: \: \: \:$

$\small\tt{No. \: of \: rows \: \: and \: \: no. \: of \: columns = 46}$

$\small\tt \blue{5 \: students} \small \tt{ \: are \: left \: out \: in \: this \: arrangement}$
