If the one side of the smaller polygon is 2 and the same side of the larger polygon is 5, than there is a ratio of 2 1/2. Meaning, that since the area of the small polygon is 20, the area of the larger polygon must be 50.
Reason:
20 x 2 1/2
20 + 20 + 10 = 50
Answer:
C) 50
Let me know if I'm wrong. I did the math in my head, so I'm not 100% positive. Sorry if this doesn't help :(
