Understanding the Area of a Trapezoid

The video tutorial explains how to find the area of a trapezoid, a quadrilateral with one pair of parallel sides. The formula for the area is given as height multiplied by the sum of the two bases, divided by two. The video provides two example problems, demonstrating the step-by-step process of applying the formula. It emphasizes the importance of using the correct height, which is perpendicular to the bases, and warns against using diagonal measurements. The tutorial concludes with a call to action for viewers to like and subscribe.

What is a defining characteristic of a trapezoid?
