ABC is an equilateral triangle. P,Q and R are the midpoints of sides AB,BC and CA, respectively. If the length of the side of the triangle ABC is 8 cm, then the area of $$ \triangle PQR $$ is:

A

$$\frac{\sqrt{3}}{3}cm^{2}$$

B

$$\frac{\sqrt{3}}{4}cm^{2}$$

C

$$4\sqrt{3}cm^{2}$$

D

$$8\sqrt{3}cm^{2}$$
