7),it may be noticed that the figure can be divided into rectilinearelements by lines drawn parallel to the parallel sides of thetrapezoid. Every such element has its centroid at its middlepoint; the locus of all these points is the so-called median ; andthe centroid G of the trapezoid must lie on… … into two triangles by the diagonal BC and remember that thedistance of the centroid of a triangle from its base is equal toone-third of its height; then taking moments with respect to thetwo parallel sides AB = a, CD = b, denoting the height of thetrapezoid by k, and the distances of G from a and…
