thats because the square root of 19 is not a nice, pretty whole number. it is a nonterminating, non repeating decimal. Your calculator can only round to about 10 places. When you don't get a whole number for an answer you use the square root symbol

if you know the lengths of two sides and the angle between them it is \[\frac{1}{2}ab\sin(\theta)\]
