Answer 2

$\sf{\huge{\underline{\green{Answer :-}}}}$

The given figure is a trapezium ,

Made by an equilateral triangle & rhombous

Perimeter of an equilateral triangle =

➝3a

➝ 3 × 12

➝ 36 cm

Now, The perimeter of rhombus =

➝ 4a

➝ 4 × 12

➝ 48 cm

The perimeter of following figure =

➝ Perimeter of an equilateral triangle + Perimeter of rhombus

➝ 36 + 48

➝ 84 cm

Hence, The perimeter of given figure is 84 cm .
