    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.

    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.
