Question 15A triangle in the coordinate plane has vertices $A(\log_2 1, \log_2 2),$ $B(\log_2 3, \log_2 4),$ and $C(\log_2 7, \log_2 8).$ What is the area of $\triangle ABC?$$\log_2 \dfrac{\sqrt3}{7}$$\log_2 \dfrac{3}{\sqrt7}$$\log_2 \dfrac{7}{\sqrt3}$$\log_2 \dfrac{11}{\sqrt7}$$\log_2 \dfrac{11}{\sqrt3}$
