In this challenge, you have to find the distance between two points placed on a Cartesian plane. Knowing the coordinates of both the points, you have to apply the Pythagorean theorem to find the distance between them.

Two points on a Cartesian plane

Given two hashes a and b being the two points coordinates (x and y), implement a function that returns the distance between the points, rounded to the nearest thousandth.

Examples

get_distance({"x" => -2, "y" => 1}, {"x" => 4, "y" => 3}) ➞ 6.325

get_distance({"x" => 0, "y" => 0}, {"x" => 1, "y" => 1}) ➞ 1.414

get_distance({"x" => 10, "y" => -5}, {"x" => 8, "y" => 16}) ➞ 21.095

Notes

  • Take a look at the Resources tab if you need a refresher on the geometry related to this challenge.
  • The "distance" is the shortest distance between the two points, or the straight line generated from a to b.
