Answer 2

Answer:

Perimeter of equilateral triangle = 3 × side

It is given that perimeter of equilateral triangle is 60cm. So,

Perimeter of equilateral triangle = 3 × side

60 = 3 × side

So,. side = 60/3cm

Therefore, side of equilateral triangle = 20

Area of equilateral triangle = √3/4 × a²

= √3/4 × (20)²

= √3 × 100

= 100√3cm²
