Answer 2

Answer:

$Number \:of \: rows \: in \: the \: Auditorium = \green {89}$

Step-by-step explanation:

$Let \: number \: of \: soldiers \:sat \: in \: a\\row = \blue {x}$

$number \: of \: rows\: in \: a\\Auditorium = \blue {x}$

$Total \: soldiers \: sat \: in \: an \: Auditorium = 7921$

$\implies \blue { x \times x } = 7921$

$\implies \blue { x^{2} }= 7921$

$\implies \blue {x} = \sqrt{7921}$

$\implies \blue {x } = \sqrt{89\times 89}$

$= 89$

Therefore.,

$Number \:of \: rows \: in \: the \: Auditorium = \green {89}$
