To find the perimeter of a shape, you need to add up the lengths of all its sides. For example, to find the perimeter of a rectangle, you would add the lengths of its four sides together. The formula for perimeter varies depending on the shape you are working with.
To find the distance around the shape
You find perimeter by adding all the sides of a figure.
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.
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.
The perimeter would be 26cm.
