Q64. Let $A B C$ be an equilateral triangle. A new triangle is formed by joining the middle points of all sides of the triangle $A B C$ and the same process is repeated infinitely many times. If P is the sum of perimeters and $Q$ is be the sum of areas of all the triangles formed in this process, then : (1) $\mathrm { P } ^ { 2 } = 6 \sqrt { 3 } \mathrm { Q }$ (2) $\mathrm { P } ^ { 2 } = 36 \sqrt { 3 } \mathrm { Q }$ (3) $P = 36 \sqrt { 3 } Q ^ { 2 }$ (4) $\mathrm { P } ^ { 2 } = 72 \sqrt { 3 } \mathrm { Q }$
