# Find the distance between the points (0, 0) and (36, 15). Can you now find the distance between the two towns A and B discussed in Section 7.2.

Answer :

The coordinates of point A are (0, 0) and coordinates of point B are (36, 15).
To find the distance between them, we use Distance formula:
d = $$\sqrt{(36-0)^2 + (15 - 0)^2}$$
$$= \sqrt{36^2 - 15^2}$$
$$= \sqrt{1296 + 225}$$
$$= \sqrt{1521}$$
$$= 39$$km
