4th test is:

3
0 0
9999 10000
9998 9999

So double should be used instead of float...When I replaced float with double my code passed this test...
And, the answer should be 28283

thats wroung answer for that test ! - you shouldn't add to the sum same distance twice !!  ans is 14141 !

No! Right answer is 28283, because the points are not placing on one line.
