What is the perimeter of the parallelogram?

Possible Answers:

17 feet

40 feet

12 feet

26 feet

13 feet

Correct answer:

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 #14 : Plane Geometry

What is the perimeter of the parallelogram?

Possible Answers:

20 millimeters

26 millimeters

40 millimeters

42 millimeters

72 millimeters

Correct answer:

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.
