Therefore,

Example Question #1 : How To Find The Area Of A Parallelogram

You can solve the area of a parallelogram when you know the lengths of each of the sides. True or False?

Explanation:

The area of a parallelogram is found by computing .  In this situation, you would have the base which is the bottom side but you would not have the height measurement.  Since you would not be able to solve for the area with just the side lengths, the statement is .

Example Question #6 : Parallelograms

If a parallelogram has side lengths of  and , what is the area?

Cannot be determined.

Cannot be determined.

Explanation:

To find the area of a parallelogram, you use the formula,

.

Since the height in this problem is not known, you cannot solve for area.

Example Question #2101 : Isee Middle Level (Grades 7 8) Mathematics Achievement

Find the area of a parallelogram with a base of 6 inches and a height of 9 inches.

Explanation:

To find the area of a parallelogram, we will use the following formula:

where is the base and h is the height of the parallelogram.

Now, we know the base has a length of 6 inches. We also know it has a height of 9 inches.  Knowing this, we can substitute into the formula.  We get

Example Question #8 : Parallelograms
