Let $△ABC$ be an equilateral triangle. Extend side $AB$ beyond $B$ to a point $B^{\prime }$ so that $B{B}^{\prime }=2\cdot AB$. Similarly extend side $BC$ beyond $C$ to a point $C^{\prime }$ so that $C{C}^{\prime }=2\cdot BC$ and extend side $CA$ beyond $A$ to a point $A^{\prime }$ so that $A{A}^{\prime }=2\cdot CA$. What is the ratio of the area of $△A^{\prime }{B}^{\prime }{C}^{\prime }$ to the area of $△ABC$?
