Areas of Polygons

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

    (I have attached the problem to this post as a file)

    2. Relevant equations

    In class we learned other fomulas for the area of a triangle using the SAS case, ASA and SSS (Heron's).

    3. The attempt at a solution

    I am honestly so confused with this one. I have a bunch of random facts that are basically given in the question like [AFB]/[FEB] = AF/FE = 1. That CD/DE = 1/4. But I can't even solve (a). Any help or hints would be really appreciated.

    I've never seen the square bracket notation before, but I'm guessing that [ABC] would mean the angle at B subtended by the lines AB and BC?

    So when the question says that [BDG] = 2, it's 2 what? 2 degrees?

    Oh sorry! I didn't know if that was standard notation or not... It just means the area of that shape :)
