Question

if the perimeter of a equilateral triangle is 60m . Then find the area​

Answer 1

Answer:

hiiii

Step-by-step explanation:

Let each side of an equilateral be x.

Then, perimeter of an equilateral triangle = 60 m

x + x + x = 60 ⇒ 3x = 60 ⇒ x = 60/3 = 20 m

Area of an equilateral triangle = √3/4 (Side)2 = (√3/4) x 20 x 20 = 100 √3 m2

Thus, the area of triangle is 100√3 m2.
