A) \[7:6\]
B) \[6:7\]
C) \[3:7\]
D) \[7:3\]
Correct Answer: B
Solution :
Let the length and breadth of the rectangle be \[3x\] and \[2x\] cm respectively. Perimeter of rectangle \[\therefore \] \[2\,(3x+2x)=40\] \[\Rightarrow \]\[10x=40\] \[\Rightarrow \]\[x\,=\frac{40}{10}=4\] \[\therefore \] Area of the rectangle \[=3x\,\,\,\,\,\,2x\] \[=6{{x}^{2}}\,=\,(6\,\,\,\,\,\,{{4}^{2}})\]cm2 \[=\text{ }96\]cm2
