Example Question #1 : How To Find A Parallelogram On A Coordinate Plane

New_vt_custom_xy_plane5

The parallelogram shown above has a height of  and a base of length . Find the perimeter of the parallelogram.

Possible Answers:

Correct answer:

Explanation:

In order to find the correct perimeter of the parallelogram apply the formula: , where  the length of one of the diagonal sides and  the length of the base. 

In order to find the length of side , apply the formula: . By drawing an altitude from point  to , a right triangle is formed with a base that has a length of  and a height of .

Thus, the solution is:

 length of side 




Therefore,
