Polygons: Areas Homework Help & Hints

Homework Statement

Homework Equations

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

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 :)
