Understanding the Area of a Parallelogram

This video tutorial explains how to find the area of a parallelogram using the formula base times height. It provides three examples, including one that uses the Pythagorean theorem to find the height. The video emphasizes the importance of knowing the base and height to calculate the area accurately.

What two measurements are needed to calculate the area of a parallelogram?

• Perimeter and height

• Diagonal and side

• Base and height

• Length and width

If a parallelogram has a base of 30 and a height of 15, what is its area?

• 400 square units

• 500 square units

• 300 square units

• 450 square units

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

• Base divided by height

• Base times height

• Base plus height

• Base minus height

For a parallelogram with a base of 20 and a height of 25, what is the area?

• 400 square units

• 450 square units

• 500 square units

• 550 square units

What is the first step in finding the height of a parallelogram when given sides of 11, 13, and 6?

• Subtract the smaller side from the larger side

• Add all sides together

• Use the Pythagorean theorem

• Divide the base by the height

In the context of the Pythagorean theorem, what does 'c' represent?

• The base

• The height

• The hypotenuse

• The area

What is the value of the missing side when using the Pythagorean theorem with sides 5 and 13?

• 12

• 11

• 10

• 13

After finding the height using the Pythagorean theorem, what is the next step to find the area?

• Multiply the base by the height

• Divide the base by the height

• Add the base and height

• Subtract the height from the base

What is the area of a parallelogram with a base of 11 and a height of 12?

• 156 square units

• 132 square units

• 120 square units

• 144 square units

Which theorem is used to find the height in the third example?

• Base theorem

• Pythagorean theorem

• Area theorem

• Height theorem
