Answer 2

To Find:-

$\sf\bold \green{Primete r \: of \: square }$

Formula used:-

$\boxed{Perimeter of square =4×side}$

Perimeter of First square :-

$\sf \rightarrow perimeter \: = 4 \times 3cm \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 12cm$

Perimeter of second square:-

$\sf \rightarrow \:perimeter \: = 4 \times 5cm \\ \sf \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 20cm$

Perimeter of third square:-

$\sf \rightarrow \: perimeter = 4 \times 8cm \\ \: \sf \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 32cm$
