Why would you need to separate a figure into parts to calculate perimeter and 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.


What is a composite figures perimeter?

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.

How do you calculate the area and perimeter of shapes?

To calculate the area you multiply the width times lenghth.the numbers that are on the side of the shape multiply them and you'll get the area. Now to get the perimeter you add the numbers on the sides together. Add lenght times width.that's how you get your perimter and area.
