To find the perimeter of a shape, you need to add up the lengths of all its sides. For example, in a rectangle, you would add together the lengths of the two shorter sides and the two longer sides. In a triangle, you would add the lengths of all three sides. The formula for finding the perimeter of a shape depends on the specific shape you are working with.

Well, finding the perimeter is just like taking a little walk around the outside of a shape. You just add up all the sides together, like counting your steps as you walk. It's a lovely way to appreciate the boundaries of a shape and see how everything fits together harmoniously.
The area is the length times the width. The perimeter is two times the length plus two times the width.
multiplying. adding is permeter. sorry bout my spelling. not the best at it
Add all the sides of the irregular figure to the obtain the perieter. In the this particular case the permeter will be 2+3+4+9 =18 cms.
The perimeter is all the way around the shape so it would be.. 16 + 16 + 2 + 2 = 36. Therefore th perimeter must be 36cm.
