Answer 2

Answer:

$Given, \: \\ l = 18.6 \: cm \: and \: b = 12.4 \: cm$

$Perimeter = 2(l + b)$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 2(18.6 + 12.4) \: cm$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 2 \times 31 \: cm$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 62 \: cm$
