Perimeter and Area
How to work them out.
What is perimeter?
Perimeter is the distance around a two-dimensional shape. It can be measure by adding up the distance of all sides of a shape. For more information check out the website link below.
What is area?
To help you understand an area, imagine painting it and how much paint you might use. Area can be worked out by multiplying the length of a shape by its height.
Length x Width = Area
You can sometimes break a shape up into two or more simpler shapes and after finding the area for each shape you add the areas together to find the total area.
