Perimeter of Polygons
Let’s take our perimeter of polygons quiz and test your knowledge!
Each side of the shape is measured only once when calculating the perimeter. No unmeasured side is left.
Starting from one corner of the shape, we count the units between each two points in order. Thus, we find that the perimeter of the shape is 24 units. Likewise, you can calculate the length of your desk with a pencil and find the perimeter.
Perimeter of Rectangle
When calculating the perimeter of a rectangle, we add its short and long sides and multiply the result by two.
Perimeter of Square
When calculating the perimeter of a square, we multiply one side by four.
