How to Find the Area of a Parallelogram (Mathematics Lesson)

How to Find the Area of a Parallelogram

The area of a parallelogram is found using the formula:



In this formula, b is the length of the base of the parallelogram and h is the height of the parallelogram. The image below shows what we mean by the length of the base and the height:

A Real Example of How to Find the Area of a Parallelogram

An Example Question

What is the area of a parallelogram with a base 8 cm and a height of 3 cm, as shown below?

Step 1
Start with the formula:
Area = bh
Don't forget: bh = b × h

Step 2
Substitute the length of the base and the height into the formula. In our example, b = 8 and h = 3.
Area = 8 × 3 = 24 cm2
The area of the parallelogram with a base of 8 cm and a height of 3 cm is 24 cm2.
