Calculating Area of Parallelograms

Mr. Buffington introduces the concept of calculating the area of a parallelogram. He explains that the area is found using the formula base times height, similar to a rectangle. The video includes an animation to demonstrate why this formula works and provides practice questions to reinforce the concept. Students are encouraged to identify the base and height among given measurements and apply the formula to find the area. The lesson concludes with additional practice suggestions.
