Question

the perimeters of equilateral triangle 60 m ffind it's area​

Answer 1

Answer:

100 root3 m²

Step-by-step explanation:

Perimeter of equilateral triangle = 3 × side

Given Perimeter = 60 m

Side of triangle = (60÷3) m = 20 m

Area of equilateral triangle = root3 / 4 × (side)²

=> Area = root3 / 4 × (20)² = root3 × 100 = 100 root3 m²

Answer 2

100 root3 m² is the right answer
