How to Find the Area of a Parallelogram

The video tutorial explains how to calculate the area of a parallelogram using the formula A = BH, where B is the base and H is the height. The instructor introduces a practice problem involving a parallelogram drawn by Jana, prompting viewers to pause the video and solve it. After resuming, the instructor walks through the solution, identifying the base and height, and calculating the area as 72 square inches. The lesson concludes with a recap of the key points, emphasizing the perpendicular relationship between base and height.

What is the formula used to calculate the area of a parallelogram?

• A = BH

• A = B + H

• A = 2B + H

• A = B/H

How do you determine the base of a parallelogram?

• By measuring the diagonal

• By finding the longest side

• By adding the lengths of two sides

• By measuring the height

What characteristic of the height is crucial in a parallelogram?

• It is parallel to the base

• It is equal to the base

• It is perpendicular to the base

• It is longer than the base

If the base of a parallelogram is 9 inches and the height is 8 inches, what is the area?

• 81 square inches

• 90 square inches

• 64 square inches

• 72 square inches

Why is it important to ensure the height is perpendicular to the base when calculating the area of a parallelogram?

• To apply the formula A = BH accurately

• To calculate the perimeter

• To ensure the base is measured correctly

• To find the longest side
