A) 11 cm
B) 10 cm
C) 6 cm
D) 7 cm
Correct Answer: B
Solution :
Perimeter of \[\Delta \,ABC=AB+BC+AC\] \[=AB+(BP+PC)+AC\] \[=(AB+BQ)+(CR+AC)\] \[\left\{ \begin{align} & \because \,\,\,\,\,BP=BQ \\ & PC=CR \\ \end{align} \right\}\] \[=AQ+AR\] (\[\because \]AQ = AR, tangents of circle from same point A) \[=2\text{ }AQ=2\times 5=10\text{ }cm\]You need to login to perform this action.
