# 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

To find:  Distance between two points
Given:  Points A(0, 0), B(36, 15)

For two points A(x1, y1) and B(x2, y2),

Distance is given by

f = [(x2 - x1)2 + (y2 - y1)2]1/2

Distance between (0, 0) and (36, 15) is:

f = [(36 – 0)2 + (15 – 0)2]1/2

= [1296 + 225]1/2 = (1521)1/2

= 39

Hence Distance between points A and B is 39 units

Yes, we can find the distance between the given towns A and B. Let us take town A at origin point (0, 0)

Hence, town B will be at point (36, 15) with respect to town A

And, as calculated above, the distance between town A and B will be 39 km
