Example Questions

Example Question #1 : Parallelograms

A parallelogram has a side length of .  It also has a side length of .  Calculate the perimeter. 

Possible Answers:

Correct answer:

Explanation:

A parallelogram has four sides and its opposite sides are equal in length.  Therefore, if it has one side length of, it also has another side length of of .  Since we know one of its side lenghts is , then the remaining side is .  We can add all 4 side lengths to calculate the perimeter. 

Example Question #2 : Parallelograms

What is the perimeter of a parallelogram if the base is , the other side is , and the height is ?

Possible Answers:

Correct answer:

Explanation:

The perimeter of a parallelogram is the sum of all four sides or the sum of two times each side length.  The side lengths are  and  so the perimeter is .

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

Untitled_10

What is the area of the parallelogram ABCD?

Possible Answers:

Correct answer:

Explanation:

A parallelogram's area is found by multiplying its height by the base. The height of the parallelogram is not the side. It is the line that makes a right angle with the base. Therefore, the area of this parallelogram is:

Example Question #3 : Parallelograms

Untitled_11

What is the area of parallelogram ABCD?

Possible Answers:

Correct answer:

Explanation:

A parallelogram's area is found by multiplying its height by the base. The height of the parallelogram is not the side. It is the line that makes a right angle with the base. Therefore, the area of this parallelogram is:
