    Given: Base of an isosceles triangle = 20 cm, side = 40 cm

    Formula: Centroid = Height of isosceles triangle (h) / 3

    Solution:



    - O is the centroid of triangle PQR.

    - Height of triangle = √(40)2 - (10)2

    = 38.72 cm

    Centroid of triangle along y – axis = h / 3

    = 38.72 / 3

    = 12.90 cm
