Question

findthe distance between the pair of points (2,3) ,. (4,1)

Answer 1

The formula is the square root of sim of squares of difference in abscissa and ordinate.

=> Ans = √{(4-2)^2+(1-3)^2} =√(4+4 = √8 = 2√2

Answer 2

let A = ( 2,3)

B = ( 4,1)

distance between A and B =
underroot (4-2)^2 + (1-3)^2

= 2 root 2
