A) 150 metres
B) 300 metres
C) 470 metres
D) 500 metres
Correct Answer: B
Solution :
(b): \[AC=\sqrt{A{{B}^{2}}+B{{C}^{2}}}=\sqrt{A{{B}^{2}}+Q{{R}^{2}}}\] (Since\[BC=QR\] by congruency) \[=\sqrt{{{70}^{2}}+{{240}^{2}}}=250m;\] \[AP=AC-PC=250-200=50\] Also, \[CR=AP=50\] \[\Rightarrow AR=AC+CR\] \[=250+50\] \[=300\]You need to login to perform this action.
