A) 4 cm
B) 5.5 cm
C) 4:5 cm
D) 3.5 cm
Correct Answer: C
Solution :
\[\Delta ADF\] and \[\Delta ABG\] are similar, \[\therefore \] \[\frac{AG}{AF}=\frac{BG}{DF}\] \[\Rightarrow \] \[\frac{12}{9}=\frac{6}{DF}\] \[\Rightarrow \] \[12\times DF=6\times 9\] \[\Rightarrow \] \[DF=\frac{6\times 9}{12}\] \[=~\,4.5\,cm\]You need to login to perform this action.
