Area of Quadrilaterals

This video tutorial covers the calculation of areas for different quadrilaterals, including parallelograms, trapezoids, and rhombuses. It explains the formulas for each shape and provides practice problems to reinforce learning. The session concludes with a summary and a preview of the next topic, which is the area of triangles.
