Question
**Title: Calculating the Centroid and Moment of Inertia**

**Objective:**
To find the centroid and moment of inertia about the x and y axes for the given geometric shape.

**Description:**
The diagram depicts a composite shape made of rectangles. There are two primary rectangles:

1. **Upper Rectangle:**
   - Height: 15 inches
   - Length: Unspecified (part of the longer base rectangle)
   
2. **Lower Rectangle (Base):**
   - Total Length: 60 inches 
   - Height: 34 inches
   - Comprised of three segments: two 24-inch segments on the sides and a 12-inch segment in the middle.

**Axes:**
- The \(x\)-axis runs horizontally along the base of the lower rectangle.
- The \(y\)-axis is vertical, intersecting the base rectangle.

**Task:**
- Determine the centroid (geometric center) of the shape.
- Calculate the moment of inertia about the x and y axes, which are critical for understanding the distribution of mass and structural integrity when the object is under stress.
