Calculating Areas of Regular Polygons

This video tutorial explains how to calculate the area of regular polygons, including hexagons, pentagons, and equilateral triangles, using various methods. It covers scenarios where the apothem, side length, or radius is provided, and demonstrates calculations using trigonometry and geometry. The video also provides step-by-step examples for each type of polygon, ensuring a comprehensive understanding of the topic.

What is the formula to calculate the area of a regular polygon?

• Area = 0.5 * apothem * perimeter

• Area = apothem / perimeter

• Area = apothem + perimeter

• Area = perimeter / apothem
