To find the center of gravity of the resulting lamina, we will use the principle of moments by considering the original square and subtracting the removed square section. Step 1: Define the coordinate system and properties of the original square. Let the vertex A of the square ABCD be at the origin (0,0). Given AB = 4a and BC = 4a, the vertices are: A = (0,0) B = (4a,0) C = (4a,4a) D = (0,4a) The area of the original square ABCD, A_1, is (4a)^2 = 16a^2. The center of gravity of the original square, G_1, is at its geometric center: $
