A tetrahedron (triangular pyramid)
A rectangular pyramid,
A pentagonal pyramid,
A hexagonal pyramid,
A heptagonal pyramid,
An octagonal pyramid,
A nonagonal pyramid,
the list is endless.
Plus you can have prisms for each of the above.
Then there are the sphere, ellipsoid, cone.
Not forgetting irregular and concave shapes.
A septagon or a heptagon

All shapes have areas that are in square units so there is nothing you need do there. So all you need is a closed shape with a perimeter of 7 units.

A hexagon is a 6 sided polygon and a heptagon is a 7 sided polygon.
It depends on the 7 shapes that you start with.
3d + 8 = 2d - 7 3d -2d = -8 - 7 1d = - 15 d = -15
There are 34 topographically distinct convex heptahedra. And since there is no such thing as a prisim, there are 40 distinct 3d shapes with seven sides. There are other (concave or not simply connected) heptahedra as well.See the link for images.There are 34 topographically distinct convex heptahedra.

3d+8=2d-7 3d+8-8=2d-7-8 (substract 8 on both side) 3d=2d-15 3d-2d=2d-2d-15 (substract 2d on both side) d=-15
A Pyramid is a 7 lettered 3D shape with triangular faces.
No, they are the same factor since each is a multiple (-1 times) the other.

well if you take octagon (8 sides) , in 3d shapes octagon is probably called octagonal prism. and the sides are actually called faces. AND a 7 sided shape , a heptagon, is called heptagonal prism
Heptagon.
A heptagon.
A Heptagon is a 3d object with 7 faces. An example of a heptagon is a hexagonal pyramid (that is a pyramid with a hexagon for the base).
A hexagonal pyramid.
