Question 124
In the parallelogram $ABCD$ ($BC \parallel AD$) the side $AB$ is half as long as the side $BC$. The bisector of the angle $ABC$ intersects the side $AD$ at $K$ and the diagonal $AC$ at $L$. The bisector of the angle $ADC$ intersects the extension of the side $AB$ beyond $B$ at the point $M$. The line $ML$ intersects the side $AD$ at $F$.
Find the ratio $AF : AD$.
