Finding the Area of Trapezoids

The video tutorial explains how to calculate the area of a trapezoid using its bases and height. It introduces the trapezoid as a quadrilateral with two parallel sides and provides the formula for area calculation. The tutorial includes multiple examples, demonstrating how to find the area when given different sets of information, such as missing bases or height. Each example is solved step-by-step, reinforcing the understanding of the formula and its application.
