Heptagonal is an adjective, not a noun! The answer will depend on whether you mean a heptagonal pyramid, a heptagonal bipyramid, a heptagonal prism or whatever.
In a heptagonal prism, there are 7 rectangular lateral faces along with 2 heptagonal bases. The rectangular faces have edges that are perpendicular to the edges of the heptagonal bases. Therefore, there are 7 faces with perpendicular edges in a heptagonal prism.
A heptagonal what? Prism, pyramid or something else?
Nine.
Faces = 8 Edges = 14 Corners = 8
Faces: 14 Vertices: 9 Edges: 21
a heptagonal pyramid has 8 faces

An heptagonal based prism, also known as a heptagonal prism, has two faces that are perpendicular to each other. These faces are the bases of the prism, which are heptagons in this case. The perpendicular edges are the edges that connect the vertices of the bases at right angles, resulting in a total of 14 perpendicular edges in a heptagonal prism.
Faces = 8 Edges = 14 Corners = 8
