Example Question #1 : Parallelograms

Ted drew the parallelogram shown below.

What is the perimeter of the parallelogram?

12 feet

26 feet

17 feet

40 feet

13 feet

26 feet

Explanation:

The perimeter of a parallelogram can be found by summing the lengths of each of the sides.  In a parallelogram, opposite sides have the same length.  Therefore, you should use the equation 8 + 8 + 5 + 5 = P.  The perimeter of the parallelogram is 26 feet.

Example Question #2 : Parallelograms

Guillermo drew the parallelogram below.

What is the perimeter of the parallelogram?

26 millimeters

72 millimeters

42 millimeters

40 millimeters

20 millimeters

40 millimeters

Explanation:

The perimeter of a parallelogram can be found by summing the lengths of each of the sides.  In a parallelogram, opposite sides have the same length.  Therefore, you should use the equation 8 + 8 + 12 + 12 = P.  The perimeter of the parallelogram is 40 feet.
