How do I get the answer for #2. What’s the equation to get to the answer please?

Answer:
GED=2FED. Multiply by 2.
Step-by-step explanation:
The page says that the diagram is not to scale, and that EF bisects(cuts in half equally) GED. Don't go by what it looks like, FED and FEG are equal in size. So each one is 1/2 of GED.
