A) \[160\,\,{{m}^{2}}\]
B) \[180\,\,{{m}^{2}}\]
C) \[20\,\,{{m}^{2}}\]
D) \[200\,\,{{m}^{2}}\]
Correct Answer: D
Solution :
Let the breadth of rectangle be \[x\] metre the perimeter \[=2x+4x\] \[=6x=60\,\,m\] \[x=\frac{60}{6}=10\,\,m\] \[\because \] \[Breadth\,\,x=10\,\,metre\] \[\because \] \[Length=10\times 2=20\,\,metre\] Area of the rectangle \[=10\times ~20=200\,\,square\,\,metre\]You need to login to perform this action.
