Let the given points be A(2, 3) and B(4, 1).
We know that the distance between two points A(x₁, y₁) and B(x₂, y₂) is given by
AB  = 

Let the given points be A(-5, 7) and B(-1, 3).
Let the given points be A(-5, 7) and B(-1, 3).

Let the given points be A (a, b) and B(-a, -b)
We know that the distance between two points A (a, b) and B(-a, -b) is given by

Let the given points be A(0, 0) and B(36, 15) then,

Yes, we can find the distance between the two towns A and B discussed in section 7.2 and this distance = 39 km.
