M10, 31 - Parallelogram [#permalink]

If the area of a parallelogram is 100, what is the perimeter of the parallelogram?

1. The base of the parallelogram is 10.
2. One of the angles of the parallelogram is 45 degrees.

Explanation states that we can use Pythagorean theorem to find third side. I am not able to visualize this. To reconfirm, I checked the definition at http://www.mathopenref.com/parallelogram.html

Am I missing something?
