A) \[250\,\,{{m}^{2}}\]
B) \[300\,\,{{m}^{2}}\]
C) \[210\,\,{{m}^{2}}\]
D) \[240\,\,{{m}^{2}}\]
Correct Answer: D
Solution :
Let length and breadth of a rectangle are 5x And 3x Then, \[5x=3x+8\] \[5x-3x=8\] \[2x=8\] \[x=4\] Now, length \[=5x=20\,\,m\] and breadth\[=3x=3\times 4\] \[=12\,\,m\] Hence, area of rectangle\[=length\times breadth\] \[=20\times 12\] \[=240\,\,{{m}^{2}}\]
