Question

Find the distance between the following pair of point (2, 3), (4, 1)

 

Answer 1

Distance between the points is given by

`sqrt((x_1 - x_2)^2 + (y_1 - y_2)^2)`

Therefore the distance between (2,3) and (4,1) is given by

`l =  sqrt((2 - 4)^2 + (3 -1)^2)`

`= sqrt((-2)^2 + (2)^2)`

`=sqrt(4+4) = sqrt8 = 2sqrt2`
