Let's break down the math problem from the image:

### Part D:
- **Problem Setup**: We are given a 2-inch mat surrounding the canvas. To find the external dimensions of the mat, the calculations indicate:
    - Mat width = Canvas width + (2 × 2 inches) = Canvas width + 4 inches.
    - Mat height = Canvas height + 4 inches.
    - Then, with a 4-inch frame around the mat, the external dimensions of the framed picture would be:
      - Framed width = Mat width + 2 × 4 = Mat width + 8 inches.
      - Framed height = Mat height + 8 inches.

- **Given Canvas Dimensions**:
  - \( \text{Canvas width} = 9.22 \) inches,
  - \( \text{Canvas height} = 55.32 \) inches.
  
- **Calculation for Framed Dimensions**:
  - **Framed Width** = \( 9.22 + 8 \) inches = **17.22** inches.
  - **Framed Height** = \( 55.32 + 8 \) inches = **63.32** inches.

The diagram shows the breakdown of these calculations along with the frame and mat dimensions.

### Part E:
- **Support Setup**: The support is installed at specific intervals along the edge of the frame. The intervals mentioned in the image:
    - At 0 inches from the left edge.
    - At 13 inches from the left edge.
    - At 23 inches from the left edge.
    - At the right edge of the frame, given as the total width of 17.23 inches.
  
The sketch shows support placement at these intervals along the frame's width.

### Part F:
- **Positioning the Canvas with respect to the Ceiling**: The canvas is positioned 36 inches below the ceiling. We are given a total width for the canvas (denoted as "W") and the information that the left edge is positioned \( \frac{W}{2} \) inches from the centerline.

- **Coordinate System**: A coordinate system can represent the frame, where:
    - The x-axis is the distance below the ceiling.
    - The y-axis represents the height of the wall.

---

This seems to be a framing and positioning problem involving a mat, a canvas, and its placement relative to the wall and ceiling. The steps and calculations provided look correct, but it is important to verify the total width (W) mentioned in part F if it was supposed to be given.

Do you want more details on these calculations or have any specific questions?

### Related Questions:
1. What is the final framed width if the frame's thickness was larger?
2. How would the positions of the supports change if the frame width were altered?
3. How is the centerline of the frame related to the support placements?
4. Could the coordinate system in part F be expanded to include depth for 3D positioning?
5. How would the calculations change if the mat were 3 inches instead of 2?

### Tip:
When working with frame and mat measurements, always double-check each additional layer (mat, frame) to ensure that cumulative dimensions are accounted for properly.

If a 2-inch mat border surrounds the canvas, the external dimensions of the mat and frame are calculated along with the placement of supports and positioning of the canvas relative to the ceiling.
