Answer:

Hey there! ☺☻☺

\begin{gathered}\text{Side measures are different, hence it's in shape of rectangle.}\\\text{Two adjacent sides} = 5 \ cm \ and \ 7 \ cm \\\\Now,\\Perimeter = 2(l+b)\\~~~~~~~~~~~~~~~=2(5+7)\\~~~~~~~~~~~~~~~=2\times12\\~~~~~~~~~~~~~~~=\boxed{\boxed{\bold{24 \ cm}}}\end{gathered}

Side measures are different, hence it’s in shape of rectangle.

Two adjacent sides=5 cm and 7 cm

Now,

Perimeter=2(l+b)

=2(5+7)

=2×12

=

24 cm

Hope IT helps You! ☺☻☺
