Calculating the Area of Parallelograms

In this video, Mr. J explains how to find the area of a parallelogram using the formula 'area equals base times height'. He provides four examples to demonstrate the calculation process, emphasizing the similarity to finding the area of a rectangle. The video also explains why the formula works by visualizing the transformation of a parallelogram into a rectangle. Each example involves writing the formula, plugging in the base and height, and calculating the area. The video concludes with a recap of the key points and a reminder of the formula's application.

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

• Area = Length + Width

• Area = Base x Height

• Area = Side x Side

• Area = (Base + Height) / 2

In the first example, what are the base and height measurements?

• Base = 5 feet, Height = 2 feet

• Base = 2 feet, Height = 5 feet

• Base = 2 meters, Height = 5 meters

• Base = 5 meters, Height = 2 meters

What is the area of the parallelogram in the first example?

• 7 square feet

• 10 square feet

• 20 square feet

• 15 square feet
