The video tutorial explains how to find the area of a trapezoid on a coordinate plane. It begins with an introduction to the concept and then moves on to graphing trapezoid ABCD. The area formula for a trapezoid is explained, followed by a step-by-step calculation of the base lengths and height. Finally, the video demonstrates how to plug these values into the formula to find the area, resulting in 27.5 square units.
