Add All The Sides Up
You add up the length and the width :)
Simple, Add all the sides of the shape up.
All you do is add up all the sides to find the perimeter even though it is a odd shape
-- Measure or figure out the length of each side. -- Add up all the lengths of all the sides. -- The answer is the perimeter of the shape.
you add up the distance of all the sides
by multiplying 15 and 12 twice then add up your answer and that's the perimeter
you measure all the sides and add it all up
in order to find the perimeter of a shape add up all the sides measurements
perimeter is the total ft, inches, cen.... add up to at the outside of a shape area is the total ft, inches, cen... add up to inside a sape
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.
Assuming the shape is bounded by straight lines, you add up the length of all the sides.
