physics Only one part left !!!!!! PLZ HELP

A uniform, square metal plate with side L = 3.50 cm and mass 0.087 kg is located with its lower left corner at (x, y) = (0, 0) as shown in the figure. Two squares with side length L/4 are removed from the plate.

(a) What is the x-coordinate of the center of mass?
= L/2

(b) What is the y-coordinate of the center of mass?

  1. Do this as two problems:

    find the cg with the large plate, no corner cut, then the cg of the corner that is gone.

    newCg*mass=oldCG*mass-cornercg*mass

    where cg has to be figured in x, y coordinates.
