Mark as BRAINLEST

Step-by-step explanation:

Area of a rectangle = 192 sq. cm

Circumference of a circle = 44 cm

Length of rectangle = 2 + 2(Radius of circle)

Breadth of rectangle = 8 + Side of equilateral triangle

Formula used:

Area of a rectangle = Length × Breadth

Circumference of a circle = 2 × (22/7) × Radius of circle

Calculation:

Circumference of circle = 44 cm

Radius of circle = 44 × (7/22) × (1/2) = 7 cm

Length of rectangle = 2 + (7 × 2) = 16 cm

Breadth of rectangle = 192/16 = 12 cm

Side of Equilateral triangle = 12 – 8 = 4 cm

Perimeter of the Equilateral triangle = (4 × 3) cm

⇒ 12 cm

∴ Perimeter of the Equilateral triangle is 12 cm.
