Let m1 be the α*a² and m2 be the α*a²/4 where α be the uniform mass density From the question, we have to find the centre of mass of remaining portion. Now we have Xcm = m1*x1 +m2*x2 /m1+m2=( α*a²*0 - α*a²/4*a/2)/α*a²+α*a²= -a³*α/8*4α*a²/5= -a/10There was no possibility to create a diagram

x × mass remaining = mass removed × side/total no. of unshade sides
(m-m/4) × x = (m/4)(a/3)
X=a/3
