Because the lines are perpindicular, we know it must be a right triangle.

Statement 1: Lengths could be mere micometers or just a fraction under 1/3. Insuff.

Statement 2: The hypotenuse has to be longer than 1/2. Suff.

B

St1: Length of perpendiculars could be in microns. Or teh length of third perpendicular could be either smaller or very large. The sides will be greater than the perpendicular.: INSUFF

St2: If one perpendicular is greater than 1/2 then two sides will be greater than 1/2. So perimeter will be greater than 1.

I vote for D.

Statement1: 2 of perpendicular lines are greater than 1/3.

This means 2 of the lines of ab, ac or bc are greater than 1/3.
The smallest perimeter is achieved when it's equilateral triangle. So the smallest perimeter is possible when the third side also has perpendicular 1/3. So perimeter is greater than 1.

Any one agrees ?

I think you misread the question. It says 2 of the perpendicular sides are smaller than 1/3.

Agree with B

st1:
since the _|_ line is smaller than 1/3, it only opens up for a big range of numbers. Insuff.

st2:
we know the smallest value possible for the length of one of the _|_ line... Suff to answer either Yes or No
