Homework Help: Centroid of a right angle triangle

    Hi i have a right angle tringle, base=1200m and h=400.

    I have trouble understanding on how to determine the centroid i know one side will be 2/3*x and another side would be 1/3*y. But i dont understand how to write it out.

    A friend said its 1/3*1200*400*2/3*1200, but i have no idea and think its wrong.

    My attempt: 1. 1/3*400*2/3*1200 or
    2. (0.5*400*1200)*(2/3*1200)

    please help on how to find the centroid
