Belinda needs to find the center of mass of a sculpture she has made so that it will hang in a gallery correctly. The sculpture is all in one plane and consists of various shaped uniform objects with masses and sizes as shown. The length of the rectangle is L = 1.4 m and the mass of the octagon is M = 1.7 kg. Where is the center of mass of this sculpture? Assume the thin rods connecting the larger pieces have no mass and place the reference frame origin at the top left corner of the sculpture.

( m, m)

I got the second m its ( m, -2,07m) , but i still don't know how to get the 1st one! This is how i did it:
(2*.8 + 5*0 + 2*1 + 1.4*1.7)/11 but its wrong! Why?

sorry I divided it by total mass 10.7 not eleven, but I do get wrong answer :/ !
