Count the number of vertices, edges, and faces, and then verify Euler's formula for the given graph.

To determine

**To verify:**

Euler's formula for the given graph.

**Given information:**

The graph is

**Formula used:**

__Euler's Formula: __v + f = c + 2, where f is the number of faces, v is the number of vertex and c is the number of edges.

**Verification:**

From the graph, we can observe that, there are 7 faces, 7 vertices and 12 edges...
