The formula for finding the perimiter of a rectangle is add up all of its sides
The area is the inside. The perimiter is around. If its a rectangle, to find the area you multiply the lengths of two sides
Ah, what a lovely little rectangle we have here! To find the perimeter, you simply add up all the sides. So for this 7cm by 4cm rectangle, you would add 7 + 7 + 4 + 4 to get a perimeter of 22cm. Isn't that just delightful?
be more specific area=base x height perimiter= add all sides together
In order to know the perimeter of a rectangle, you need to know both its length and its width ... two numbers. One number isn't enough. If one side of a rectangle is 22 feet, then the perimeter of the rectangle can be any number greater than 44 feet. There are an infinite number of different possibilities.
