Restate the question: triangle QRS is similar to triangle DEF ..... (If this isn't your question, then change the wording and ask it again) Then (QR/DE) = (RS/EF) = (SQ/FD)

There is not enough information to answer the question. For example, it is not even known if E, F and G are vertices of a triangle, three points on the same straight line, three points on the circumference of a circle or some exotic shape.
Yes. I have congestive dilated cardiomyopathy. In 2006 my EF was 125. My cardiologist prescribed beta blockers and meds to lower my BP. Now my EF is 135-140. I rest a lot and watch my diet carefully.

Since there is no triangle "below", all that can be said is that EF - if it is the third side of the triangle - is any length in the interval (24, 54).
The answer depends on the labels of the sides which are 19 and 12.
Use Pythagoras' theorem to find the 3rd side

I assume the corresponding sides are AB and EF, and EF is a side of the larger (second) triangle. scale factor 3 means each length of the second is 3 times as long as the first. ⇒ if AB = 6 units, EF = 3 x 6 units = 18 units.
