Determine the height of a parallelogram to find the area

The video tutorial explains how to identify and calculate the area of a parallelogram. It emphasizes the importance of correctly identifying the base and height, distinguishing between slant and direct height, and using rotation to simplify the process. The tutorial concludes with a calculation of the area using the correct base and height.

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

• Base plus height

• Base divided by height

• Base times height

• Base minus height

Why can't the slant side of a parallelogram be considered as its height?

• Because it is not perpendicular to the base

• Because it is longer than the base

• Because it is parallel to the base

• Because it is shorter than the base

What is the correct way to measure the height of a parallelogram?

• Along the slant side

• Along the base

• From the base to the top perpendicularly

• From one corner to the opposite corner

What happens to the dimensions of a parallelogram when it is rotated?

• They halve

• They remain the same

• They change

• They double

In the example given, what are the base and height used to calculate the area?

• Base of 20 and height of 3

• Base of 7 and height of 20

• Base of 20 and height of 7

• Base of 3 and height of 20
