Determine the distance between point (x1, y1) and point (x2, y2), and assign the result to point distance. the calculation is: d

Ronch [10]

we are given two points as

(1.0, 2.0) and (1.0, 5.0)

so,

(x1, y1)= (1.0 , 2.0)

(x2, y2)= (1.0 , 5.0)

x1=1 , y1=2

x2=1 , y2=5

now, we can use distance formula

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

now, we can plug values

and we get

$d=\sqrt{(1-1)^2+(5-2)^2}$

$d=\sqrt{(0)^2+(3)^2}$

$d=\sqrt{(3)^2}$

$d=3$

so, distance between points is 3...........Answer
