$\huge\fcolorbox{red}{blue}{Answer}$

$\huge\star\mathfrak\red{Given}$

121

$\huge\star\mathfrak\red{solution}$

$121 - 1 = 120 \\ 120 - 3 = 117 \\ 117 - 5 = 112 \\ 112 - 7 = 105 \\ 105 - 9 = 96 \\ 96 - 11 = 85 \\ 85 - 13 = 72 \\ 72 - 15 = 57 \\ 57 - 17 = 40 \\ 40 - 19 = 21 \\ 21 - 21 = 0$

we have substracted from 121 successive odd number from 1 to 21 , and we obtained 0 in 11 step

Hence,

$\sqrt{121} = 11$
