Let us take m = mass per unit length x = m_1 x_1 + m_2 x_2 + m_3 x_3/m_1 + m_2 + m_3 y = m_1 y_1 + m_2 y_2 + m_3 y_3/m_1 + m_2 + m_3 Centroid: - x = (13 times m) (0) + (8 times m) times 4 + (7.632 times m) times (2)/13 m + 8 m + 7.632 m x = 47.264 m/28.632 m = > x = 1.65 m y = (13 m) times (6.5) + (8 m) times 13 + (7.632 m) times (13 - 13/4)/28.632 m y = 262.912 m/28.632 m y = 9.182 m
