Q. 24.2( 220 Votes )
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 :
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 unitsYes, 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
