Sundar's answer is right
The question you put states that R2 and R3 should see an admin distance of
90.
Some of the replies have suggested that you change the admin distance on R1,
however admin distance is only locally significant. If you change the
distance to 90 of the 172.168.1.0 routes on R1, R2 and R3 will still see
them as EIGRP external routes and add their own admin distance of 170. Thus
distance will not help in this situation.
In fact one does need to add the 90 on the end of the summary statement.
The summary addresses will be seen as internal to the eigrp 100 process and
thus R2 and R3 will automatically apply an admin distance of 90.

Config you need on R1 is:
int f0/0
ip summary-address eigrp 100 172.168.0.0 255.255.252.0 90
ip summary-address eigrp 100 172.168.4.0 255.255.254.0 90
Hope this helps.
