110m is the answer to the question.

Answer 2

$\huge{✪}$$\huge{\underline{\mathcal{Answer}}}$

• $\pink{\sf{Side\: of\: Square \:Field = 110 \:m}}$

$\huge{✪}$$\huge{\underline{\mathcal{Steps}}}$

Let the side of the square field be x metres.

We know that,

$\large\red{\sf{Area \:of\: Square = {side}^2\:\:or\:\:}}$ $\red{a^2}$

Given,

$\large{⇒}$Area of Square Field = 12100$m^2$

$\large{⇒}$Area of Square Field = $x^2$

$\large{⇒}$12100 $m^2$ = $x^2$

$\large{⇒}$x = $\sqrt{12100\:\:m^2}$

$\large{⇒}$x = $\sqrt{11\times11\times10\times10\:\:m^2}$

$\large{⇒}$x = 11*10 m

$\large{⇒}$x = 110 m
