How to Find the Area of a Trapezoid Using Triangles and a Rectangle

The video tutorial explains how to find the area of a trapezoid by dividing it into two triangles and a rectangle. It covers a four-part question involving figure JKLM, composed of triangle JKN and trapezoid KLMN. The tutorial guides through calculating the length of line segment NM, the area of triangle JKN, the area of trapezoid KLMN, and finally, the total area of figure JKLM.
