A) \[21\,cm\]
B) \[28\,cm\]
C) \[25\,cm\]
D) \[31\,cm\]
Correct Answer: C
Solution :
(c): \[PQ||RS\Rightarrow \angle QPO=\angle SRO\] and \[\angle OQP=\angle OSR;\] thus, \[\Delta \,OQP\cong \Delta OSR\] \[OS=7\,\,cm\] and \[PO=5.5\text{ }cm\] \[\therefore \,\,\,\,QS=7+7=14\,cm;\] \[PR=5.5+5.5=11\text{ }cm\] \[\therefore \text{ }PR+QS=11+14=25cm\]You need to login to perform this action.
