We are suppose to find distance between points and the midpoint (9,8) and (2,1)

I used the distance formula which I thought was the way I should do it.
If I should not have used this, can someone tell me what I did wrong or what formula I should have used?

d=�ã(2-9)^2+(1-8)^2
d=�ã(-7)^2+(-7)^2
d=�ã98
d=7�ã2

(9+2/2, 8+1/2)
(11/2,9/2)
