    Solution:

    Height of an equilateral triangle is given as (√3 / 2) x a, here a is the side of the triangle.

    Side of equilateral triangle = 2 m

    Therefore, height of an equilateral triangle (h) = (√3 / 2) x a

    = (√3 / 2) x 2 = 1.732

    Centroidal distance of an equilateral triangle = h / 3

    = 1.732 / 3

    = 0.577 m
