Welcome back Zerah — missed you this week. To solve this problem, we first need to find the centroid of the remaining lamina. We'll use the principle of composite areas. Part (a): The distance from AB and AD of the centroid of the remainder of the lamina. Step 1: Define a coordinate system. Let point A be the origin (0,0). The side AB lies along the x-axis. The side AD lies along the y-axis. Step 2: Calculate the area and centroid for each component shape. Rectangle ABCD: Length AB = 8a, Width AD = 4a. Area $A_R = (8a)(4a) =
