This video tutorial explains how to find the area of an irregular polygon using a coordinate plane. The process involves surrounding the polygon with a box, calculating the area of the box, and then subtracting the areas of the triangles formed around the polygon. The tutorial provides step-by-step instructions, including the use of the base and height formula for triangles. The final area of the polygon is determined by subtracting the total area of the triangles from the area of the box. The video concludes with encouragement to continue learning.
