Cut your figure into two pieces. (a square and a triangle)

You can easily find the coordinates of the center of mass of the square using symmetry arguments.

You can find the coordinates of the center of mass of the triangle using the definition of the mean

Then you can find the center of mass of the whole thing with

*r being the vectors of position. - Dec 2nd 2008, 08:21 AMbandy1989thanks
