Problem:
The area of the figure where sides AF and CD are parallel, as are sides AB and FE, and sides BC and ED, each side has length 1, and ∠FAB=∠BCD=60∘ is
Answer Choices:
A. 23​​
B. 1
C. 23​
D. 3​
E. 2
Solution:
Draw in lines BF,BE and BD. There are now 4 equilateral triangles with side length 1. (For instance, △FAB is equilateral because AF=AB=1 and ∠A=60∘.)
