14. A regular octagon $P Q R S T U V W$ has sides of length $2 \mathrm{~cm}$. When I shade the rectangles $P Q T U$ and $R S V W$, four small triangles inside the octagon remain unshaded. What is the total area, in $\mathrm{cm}^{2}$, of these four triangles?
A 1
B 2
C 4
D 6
E 8
14. C The diagram on the left shows regular octagon $P Q R S T U V W$ and the shaded rectangles, $P Q T U$ and $R S V W$. The right-hand diagram shows how the four unshaded triangles fit together to form a square of side-length $2 \mathrm{~cm}$. So the total area of these four triangles is $4 \mathrm{~cm}^{2}$.
