1. The perimeter of E and the perimeter of F are equal.
2. The ratio of the height of triangle E to the diagonal of square F is 2√3 : 3√2.
1. If the perimeter of E and F are similar then definitely E has longer side. Infact the ratio of their sides are 4 : 3. Sufficient.
2. Let us suppose E and F have side = 2 units. The ratio of height : diagonal will be √3 :2 √2.
So the ratio of height : diagonal defines the length of the sides of E and F. Sufficient
IMO C.
P.S. I did try to spend time working out the respective lengths , only to realize its not necessary. Just the fact that the fact given in eitheer choice has a bearing on the length is sufficient.
Hey kstv,
It is very important to realise that in Data Sufficiency,
you don't actually solve the question.It is found that
Data Sufficiency is the portion where test-takers can save time which can be invested in Problem-Solving.
It happens to many people that at the end of the time-limit,they couldn't attempt 4-5 questions.
One of the major reasons can be that they actually try to solve the question completely rather than only checking the sufficiency of the 2 statements.
Ofcourse,there are some trap questions in which you actually need to solve the question completely but they are very few hence for the rest of the question ,we can adopt the technique of just forming the equations,looking at what the question is asking.
It takes time and effort to explain, so if my comment helped you please press Thanks button
Just because something is hard doesn't mean you shouldn't try,it means you should just try harder.
