$\huge \mathfrak \fcolorbox{red}{red}{ \fcolorbox{yellow}{yellow}{ \fcolorbox{green}{green}{ \fcolorbox{blue}{blue}{ \fcolorbox{indig}{indigo}{ \fcolorbox{violet}{violet}{ \fcolorbox{white}{white}{ \blue{ answer} }}}}}}}$

32 cm

Step-by-step explanation:

perimeter of sector =

$\frac{ angle }{ {360}} \times 2\pi \: r + 2r$

$\frac{60 }{ {360}} \times 2 \times \frac{22}{7} \times \: 10.5 + 2 \times 10.5 \\ \frac{1}{6} \times \frac{44}{7} \times \frac{105}{10} + 21 \\ \frac{1}{1} \times \frac{11}{1} \times \frac{1}{1} + 21 \\ \frac{11}{1} + 21 \\ 11 + 21 \\ 32 \: cm$

taking pi =22/7
