A) \[182\,\,cm\]
B) \[169\,\,cm\]
C) \[196\,\,cm\]
D) \[264\,\,cm\]
Correct Answer: A
Solution :
Ratio of length and breadth\[=5:2\] Area\[=5\times 2=10\,\,sq.\,\,units\] Given area\[=1690\,\,c{{m}^{2}}\] \[10\,\,sq.\,\,units\to 1690\,\,c{{m}^{2}}\] \[1\,\,sq.unit\to \frac{1690}{10}=169\,\,cm\] \[1\,\,unit=13\,\,cm\] Perimeter\[=2\times 7\,\,units=14\,\,units\] \[\therefore \]Perimeter\[=14\times 13=182\,\,cm\]
