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.
Separate them into parts. First calculate the volume of the cylinder, then the cone and then add the results
Each side of the square is a quarter of the square's perimeter.
Yes and no. You do but you don't count those parts internal to the composite figure For example you take two squares with side of 1. each individual square has a perimiter of 4. if you put them together to form a rectangle with sides 1 and 2 you have a perimeter of 6 not the 8 that the 2 squares have individually. so you have to take away the 2 sides that disappear. Frankly it makes more sense to just add the lengths of the sides of the resultant figure than to play that game of adding then subtracting redundant numbers.
A parabola is a single curve: it does not have separate parts.
It is a line of symmetry.
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.
by adding together the area of its parts
You need to cut up your figure into several parts in shapes for which we know how to calculate areas, such as squares, rectangles, and triangles. The area of your figure is the sum of the areas of its parts.

Only a chemical reaction can separate a compound into its parts.☻
