A) \[81\,\,c{{m}^{2}}\]
B) \[64\,\,c{{m}^{2}}\]
C) \[25\,\,c{{m}^{2}}\]
D) \[96\,\,c{{m}^{2}}\]
Correct Answer: D
Solution :
Perimeter \[=10\] units Ratio of perimeter and length\[=10:3\] \[\therefore \]Breadth\[=\frac{10-2\times 3}{2}\] \[2\]units\[\to 8\,\,cm\](Given) \[1\]unit\[\to \]\[4\,\,cm\] \[3\]units\[\to 4\,\,cm\times 3=12\,\,cm=\]length Area\[\to \]\[12\,\,cm\times 8\,\,cm=96\,\,c{{m}^{2}}\]You need to login to perform this action.
