(adsbygoogle = window.adsbygoogle || []).push({}); [SOLVED] i think this should be simple, but i need help!

1. The problem statement, all variables and given/known data

this isn't really homework, but i'm having trouble figuring this problem out...

the problem says:

In this diagram, the red part has an area of 800 square centimetres.

What is the area of the green part, in square centimetres? Please round up to the nearest whole number.

2. Relevant equations

i have no idea how to solve this, since the only information they give is that the pentagon is 800 square centimeters...

3. The attempt at a solution

Well, I figured out that you could probably fold the green triangle into the pentagon, and make it 3 triangles, the 2 on the sides being congruent... but how do i figure out an area???
