The problem is otherwise an application of geometry and the distance formula. If the coordinates of the two points are x1 y1 and x2 y2 the distance equals the square root of x2 x1 squared y2 y1 squared. The distance formula is derived from the Pythagorean theorem.
The first two steps are relatively easy to follow.
Mathematically if you want to determine the distance between two points on a coordinate plane you use the distance formula. 283 Circumcentre of a triangle.
