The video tutorial explains the properties of a trapezoid, a quadrilateral with one pair of parallel sides. It introduces the formula for calculating the area of a trapezoid, which involves the lengths of the two parallel bases and the height. An example is provided with specific measurements, and the calculation is demonstrated step-by-step, including simplification using fractions. The final result of the area calculation is presented, emphasizing the importance of units in the process.
