A) 12 m
B) 24 m
C) 6 m
D) 72 m
Correct Answer: C
Solution :
Let the breadth of the rectangle be b units. The length is twice its breadth. \[\Rightarrow \]Its length = 2b units \[\therefore \] Area \[\text{=b }\!\!\times\!\!\text{ 2b sq}\]units \[\Rightarrow \text{2}\times \text{b}\times \text{b=72}\] \[\text{b }\!\!\times\!\!\text{ b=}\frac{\text{72}}{\text{2}}\] \[\Rightarrow \text{b }\!\!\times\!\!\text{ b=36=6 }\!\!\times\!\!\text{ 6}\] \[\Rightarrow \]\[\text{b=6m}\]
