Answer 1

You are taking inputs as x1, x2 then y1, y2.
Your expected output works fine if you take input as x1, y1, then x2, y2
if you input like :
1.0 5.0
7.0 9.0
(5.0-1.0) * (5-1) + (9-7) *(9-7)
= 16.0+4.0 = 20.0
sqrt(20.0) = 4.4721
if you input as :
1.0 7.0
5.0 9.0
(7.0-1.0) *(7.0-1.0) + ( 9-5 * 9-5)
= 36.0+16
= 52.0
sqrt( 52.0) = 7.2111

Answer 2

What is your sample input and expected output...?

Answer 3
