Find the distance between the pair of points. (3,-4) (5,-9)

i got 5.4.  it asked for answer to the nearest tenth and said it was wrong?  What did i do wrong?

It didn't specify for the question but I guess the answer they were looking for was in radical form.

A(x1 ,y1 ) B(x2  ,y2 ) 
distance between A & B = √(x2 -x1)2 +(y2 -y1)2   
 
(3,-4) (5,-9)
Distance between 2 given points= √(5-3)2 +(-9+4)2 =√4+25 =√29 =5.3851=5.4

your work and Meena's appears to be correct, so all I can say is that you should check that the signs of all the coordinates have been faithfully (accurately) presented.
