Find the distance between the pair of points (6.2,4.6)(4.5,0.6) i have the distance as 141.50 and their answer is 4.35. how did they get this answer i squared 141.50 and still did not get 4.35

The distance is the hypotenuse of the right triangle with a vertical leg distance of 4.6  0.6 = 4.0 and a horizontal leg distance of (4.5)  (6.2) = 1.7
The hypotenuse
= ( (4.0)^2 + (1.7)^2 )^0.5
= (16.0 + 2.89)^0.5
= 4.35
