To find the distance around the shape
P = 8s where s is the length of a side.
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 find the perimeter of a triangle by adding all the sides. There is no special rule for finding the perimeter.
(length) (times) (width) (times) (two) l x w x 2 = THE TOTAL PERIMETER OF THE 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.
