This video tutorial explains how to calculate the perimeter of an irregular polygon. It begins with an introduction to the concept of perimeter, defined as the distance around a figure. The tutorial then demonstrates how to calculate the perimeter by summing the lengths of all sides of the polygon. A step-by-step example is provided, showing the addition of side lengths to arrive at a total perimeter of 26 units. The lesson concludes with a summary of the key points covered.

What is the perimeter of a polygon?

• The number of sides of the polygon

• The distance around the polygon

• The volume of the polygon

• The area inside the polygon

What makes a polygon irregular?

• Sides and angles are not equal

• All sides are equal

• All angles are equal

• It has more than four sides

How do you calculate the perimeter of an irregular polygon?

• Subtract the shortest side from the longest side

• Divide the total area by the number of sides

• Add up the lengths of all the sides

• Multiply the length of one side by the number of sides

If a polygon has sides of lengths 5, 2, 2, 5, 4, 4, 1, and 3, what is its perimeter?
