Find the distance between the points (0, 0) and (36, 15). Can you now find the distancebetween the two towns A and B discussed in Section 7.2
Distance between (0, 0) and (36, 15) is:
l = [(36 – 0)2 + (15 – 0)2]1/2
= [1296 + 225]1/2 = (1521)1/2
= 39
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 be39 km
