Area Of Trapezoids: The formula to calculate the area of a trapezoid

The video tutorial explains how to calculate the area of a trapezoid by dividing it into two triangles. It starts by reviewing the formula for the area of a triangle, which is 1/2 base times height. The tutorial then applies this formula to two triangles formed by cutting the trapezoid along its diagonal. By adding the areas of these triangles, the area of the trapezoid is determined. The process is simplified by factoring out common terms, resulting in the formula 1/2 * H * (B1 + B2) for the trapezoid's area. The tutorial concludes by emphasizing the importance of understanding the relationship between the bases and height in these calculations.
