Answer 2

$Let \: radius \:of \:the \: sector = r \: units$

$Length \: of \:the \: arc = l \:units$

$Sector \:angle = \theta$

$Perimeter \: of \: the \: sector \\= l + r + r \\=\pink { l + 2r }\\= \orange {\frac{\theta}{360\degree } \times 2 \pi r + 2r }$

Therefore.,

$\red { Perimeter \: of \: the \: sector} \\\green { = l + 2r }$

$\orange {=\frac{\theta}{360\degree } \times 2 \pi r + 2r }$
