Please solve this centre $of$ mass question and show all your steps and formulas used for solving please: Find the mass and center $of$ mass $of$ the lamina that occiupies the region $D$ and has the given density function $p(x,y)In$ each case, sketch the region $D$:

$Dis$ the region bounded $byy=x^2,y=-x+2,$ and $y=0$;$(x,y)=x+2y.$
