Consider the floor plan below that has five rooms and twelve doors. a. Represent this as a graph with six vertices (one for each room and one for the outside) and twelve edges (one for each door). Is it possible to cross all doorways (starting anywhere), but only cross each doorway once? Do not just answer yes or no, but briefly explain why.

![**Floor Plan Analysis and Graph Theory Application**
*Consider the floor plan below that has five rooms and twelve doors.*
![Floor Plan Diagram]
The diagram shows a layout with five rooms interconnected by twelve doors. The rooms and doors create multiple paths for movement throughout the space.
**Tasks:**
a. *Represent this as a graph with six vertices (one for each room and one for the outside) and twelve edges (one for each door).*
- **Graph Representation:**
- Vertices: Represent the five rooms and the outside as nodes.
- Edges: Connect the nodes where doors exist, creating a network of paths.
b. *Is it possible to cross all doorways (starting anywhere), but only cross each doorway once? Do not just answer yes or no, but briefly explain why.*
- **Explanation:**
- Consider Eulerian Path conditions, where such a path exists if there are exactly zero or two vertices with an odd degree. Analyze the degree of each vertex (rooms and outside) to determine if such a path is feasible.
**Conclusion:**
- Evaluate the rules of graph theory to provide a conclusive answer about the possibility of traversing all doorways exactly once, starting and ending at any point.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F7157b572-b6ea-402e-940f-02951f488872%2F45fbac94-ff4d-4804-a5ad-8170fd452ed4%2Fta3rtl_processed.jpeg&w=3840&q=75)
