Lesson Summary:

In this lesson, you will learn about area formulas for various geometrical shapes such as parallelograms, triangles, and trapezoids. The area of a parallelogram is simply the base times the height, the area of a triangle is half the base times the height, while the area of a trapezoid is typically calculated as half the height times the sum of the bases. The lesson also includes practical examples and problem-solving exercises.
