You don't. Perimeter is a concept associated with plane figures, not solid shapes.
Yes - even shapes with different area.
You don't need to if you can manage to work out the perimeter and area of complex shapes. Most people cannot work easily with shapes other than triangles, quadrilaterals, circles and semicircles. For them (us) it is easier to partition the shape.
Most shapes have different perimeter than area, as far as value.
it's a subject because it explains about all types of shapes that you can know and it also teaches you how to calculate the area and perimeter of the shape that you are finding.
Oh, isn't that a happy little question! To find the perimeter of an irregular shape, you simply add up the lengths of all its sides. And to find the area, you can break the shape into smaller, simpler shapes like triangles or rectangles, and then add up their individual areas. Just remember, there are no mistakes, only happy little accidents in math and art!
Legnth of the sides and then you add them up to get the perimeter

For the area of a square, it is the base x the height, and the perimeter is 2height+2base. For the area of a triangle, it is base x height divided by two. And to find the perimeter you just add up each of the side lengths.

There are infinitely many shapes.
yes they can

Oh, what a happy little question! Let's think about shapes that could have a perimeter of 15 and an area of 16. One shape that comes to mind is a rectangle with dimensions 4 by 4. Another possibility is a square with sides of length 4. These shapes show us that there can be different ways to create beautiful combinations of perimeter and area.
They are the result of combining shapes, either by adding parts or taking parts away. We calculate the perimeter of composite shapes by splitting them into simpler pieces and then calculating the perimeter of those simpler pieces.
