"Flat shape" is a broad description that can be categorized into several more specific descriptions. For example, polygons, circles, and the outline of an irregular object such as a giraffe can all be described as flat shapes. For polygons, which are closed shapes with 3 or more straight sides, the perimeter is the sum of the lengths of the individual sides. The perimeter of a circle is pi (3.14) times the length of the diameter of the circle. A diameter is any line that connects two points on the edge of the circle and passes through the center. Other shapes have more specific perimeters, but in general, a flat shape's perimeter is the length of string that would be required to fully mark the outline of the shape.
There are many formulas for perimeter depending on what shape you are trying to find the perimeter of. The perimeter is the distance around a shape, so one formula to find perimeter is simply adding all the side lengths together.
Add All The Sides Up
perimeter is when you have a shape and then you have your area and that is what is in the middle of the shape and perimeter is the edge of the shape.
Perimeter of what? A circle diameter times Pi. Another shape the sum of all sides.
Break the composite shape down into simple units. Find the perimeter and area of each and then add these up as appropriate. If the shape cannot be broken down easily you may have to rely on integration or numerical methods.
To find the distance around the shape
Perimeter
You find perimeter by adding all the sides of a figure.
All you do is add up all the sides to find the perimeter even though it is a odd shape

how can you find the perimeter of a cone i.e. a 3d shape!
Perimeter = The sum of the lengths of all sides of a shape
When the shape is a circle, then the perimeter is called"circumference".The circumference IS the perimeter of a circle.
Anyone who has mastered the measurement of lengths and simple addition can find the perimeter of a plane shape.
You break it up into smaller shapes which are less irregular. If these are more regular, you can calculate their contribution to the perimeter, and their area. You can then add these together.
It is not possible to do so.
in order to find the perimeter of a shape add up all the sides measurements
