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

In parallelogram ABCD, if the base is 8 cm, what is the height?

• 8 cm

• 4 cm

• 5 cm

• 6 cm

Why is 5 cm not considered the height in parallelogram ABCD?

• It is not perpendicular to the base

• It is longer than the base

• It is shorter than the base

• It is parallel to the base

What is the area of parallelogram ABCD if the base is 8 cm and the height is 4 cm?

• 36 square cm

• 20 square cm

• 32 square cm

• 24 square cm

In parallelogram PQRS, what is the base length?

• 15 cm

• 21 cm

• 13 cm

• 12 cm

Which segment represents the height in parallelogram PQRS?

• Segment RS

• Segment PQ

• Segment QR

• Segment ST

Why is segment ST considered the height in parallelogram PQRS?

• It is the longest segment

• It is the shortest segment

• It forms a right angle with the base

• It is parallel to the base

What is the area of parallelogram PQRS if the base is 21 cm and the height is 12 cm?

• 242 square cm

• 252 square cm

• 262 square cm

• 272 square cm

What is the unit of measurement for area in these examples?

• Square centimeters

• Square meters

• Centimeters

• Meters

What is the importance of the right angle in determining the height of a parallelogram?

• It ensures the height is the longest side

• It helps in calculating the perimeter

• It confirms the height is perpendicular to the base

• It makes the parallelogram a rectangle
