Question

How do you find the distance between (2.3, 4.5) and (–3.4, –5.2)?

Answer 1

Distance Formula

The distance `D` between two points `(x_1,y_1)` and `(x_2,y_2)` can be found by

`D=sqrt{(x_1-x_2)^2+(y_1-y_2)^2}`

---

Let `(x_1,y_1)=(2.3,4.5)` and `(x_2,y_2)=(-3.4,-5.2)`.

`D=sqrt{[2.3-(-3.4)]^2+[4.5-(-5.2)]^2}=sqrt{126.58} approx 11.25`

I hope that this was helpful.
