Understanding the Area of Parallelograms

This video tutorial explains how to find the area of parallelograms using the formula area equals base times height. It includes two examples: parallelogram ABCD and parallelogram PQRS. For each example, the video demonstrates how to identify the base and height, ensuring the height forms a right angle with the base. The tutorial emphasizes the importance of using the correct measurements and provides step-by-step calculations to find the area in square centimeters.

What is the formula for finding the area of a parallelogram?

• Area = base x width

• Area = length x width

• Area = base x height

• Area = base + height
