The sacle factor between two shapes is the same as the ratio of their perimeters.
Any shape at all can have any perimeter at all.
Perimeters are not defined in the context of 3 d shapes.
Because the area is different than the perimeters
There is no particular reason. In fact, in general, two shapes will have different areas or perimeters or both.
Yes all shapes have perimeters.

Because the area is different than the perimeters
There are an infinite number of shapes with perimeters of 32.Even if you stuck to one shape and asked: "How many squares ..." or "How many circles ... " or "How many triangles ... ",there are still an infinite number of each shape that all have perimeters of 32.
geometry represnt shapes and it's properties where as mensuration represents calculation of shapes like areas and perimeters.
Most shapes can have the same area and different perimeters. For example the right size square and circle will have the same are but they will have different perimeters. You can draw an infinite number of triangles with the same area but different perimeters. This is before we think about all the other shapes out there.
Normally perimeters are are only applicable to 2 dimensional shapes.
With great difficulty because a cone is a 3D object and only 2D shapes have perimeters
