The perimeter is the distance around the outside of an object. It is found by adding the lengths of all of the sides of the object together.
The area is the amount of surface enclosed by a closed figure.
Area of a rectangle = length × width
Area of a square = side × side
Using these formulae, we can also compare the area or perimeter of two given figures.
For example, consider the following figures:
Let's compare their perimeters.
Perimeter of first figure = 5 + 3 + 5 = 13 feet
Perimeter of second figure = 3 + 8 + 3 = 14 feet
Now, 13 feet is less than 14 feet.
So, the perimeter of first figure is less than the perimeter of second figure.
