#Divide the shape into two rectangles, as shown in fig 2. Find the centroids of these two rectangles by drawing the diagonals. Draw a line joining the centroids. The centroid of the shape must lie on this line <math>AB.</math>
#Divide the shape into two other rectangles, as shown in fig 3. Find the centroids of these two rectangles by drawing the diagonals. Draw a line joining the centroids. The centroid of the L-shape must lie on this line <math>CD.</math>
#As the centroid of the shape must lie along <math>AB</math> and also along <math>CD,</math> it must be at the intersection of these two lines, at <math>O.</math> The point <math>O</math> might lie inside or outside the L-shaped object.
