Centre of mass is given by = (m1x1 +m2x2 +m3x3 +m4x4)/(m1+m2+m3+m4)
where m is the respective mass and x is the respective distance with respect to A ( in metres)
the diagonal of a square is 0.8 metres therefore using pythogoras law each side is of a distance 0.56 metres.
therefore centre of mass is = (8*0+2*0.56+4*0.8+2*0.56)/(8+2+4+2)=.34 metres from A
