In the figure above, what is the ratio KN / MN
1) The perimeter of rectangle KLMN is 30 meters
2) The three small rectangles have the same dimensions
Answer is B.
Can someone please explain? even if same dimensions, won't ratios be distorted with real numbers? |

1) The perimeter doesnt state anything about the length and breadth. So INSUFF
2) The three small rectangles have the same dimensions. It is also obvious in the figure that the length of one side of the smaller rectangle is twice the breadth. Hence we can insert figures like L=2 and B=1. So we get the larger rectangle length as 3 and breadth as 2. The proportion will always remain 2/3. Hence SUFF
Answer therefore B.
Hope this clears ur doubts. |
