I found the distance between them but i'm not sure i got them right...

for d and e it's 5
for e and f it's 4sqrt2
for d and f it's sqrt17
but... is that okay... 
and i have to find the area, so i have to do pythagorean theorem on 5 and sqrt of 17, but i have to divide sqrt17 by 2 and then square both of them and it's just too complicated!
i'm not sure
check the distances for me!
