The second moment of an area is always least about an axis through its centroid. If the second moment of an area, A, about an axis x from its centroid is Ix and Ixx is that about a parallel axis through the centroid:

In the above example the second moments about axes through the centroid and parallel to the x-axis and y-axis, are respectively:

Ixx — 5.82 - 9.93(0.65)2 — 1.62m4 Iyy — 182.13 - 9.93(3.73)2 — 43.97m4

Where there are large numbers of ordinates the arithmetic in the table can be simplified by halving each Simpson multiplier and then doubling the final summations so that:
