A) 240
B) 200
C) 120
D) 140
E) None of these
Correct Answer: C
Solution :
Explanation Option [c] is correct. Let ABCD be rhombus. \[\operatorname{AB}=13 cm,\] \[\operatorname{BD}=10 cm\] \[\operatorname{OB}=\frac{10}{2}= 5\,cm\] \[\therefore \,\,\,\,AO\,=\sqrt{169-25}\] \[=12\,cm\] \[\therefore \,\,\,\,AC\,=24\,cm\] \[\therefore \,\,\,\,Area\,\,of\,rhombus\,\] \[=\frac{1}{2}\times (24\times 10)=120\,sq.\,cm.\]You need to login to perform this action.
