The moment of area for a rectangle about the horizontal

Question

The parallel axis theorem: I_x = I_xc+d_y² A

The moment of area for a rectangle about the horizontal axis is: I_xc = bh³/12.

The centroid of this T-shaped region has been found to be located at a distance 36.25mm from the bottom. All dimensions are in millimeters.

Calculate the centroidal second moment of area for the T-shaped region about the x-axis.
