Area = 9√3 cm²

Perimeter = 18 cm

Explanation:

• Area of equilateral triangle ABC =

(√3/4) × 6²

= (√3/4) × 36

• ABC is an equilateral triangle with side = 6 cm

Perimeter of an equilateral triangle = AB+BC+CA

Perimeter of an equilateral triangle = 6+6+6

Perimeter of an equilateral triangle = 18 cm
