A) 56
B) 45
C) 39
D) 40
Correct Answer: C
Solution :
Let M (0, 0) and N (36, 15) be the given points. Here, \[{{x}_{1}}=0,\]\[{{y}_{1}}=0\]and \[{{x}_{2}}=36,\]\[{{y}_{2}}=15\] \[\therefore \]\[MN=\sqrt{{{({{x}_{2}}-{{x}_{1}})}^{2}}+{{({{y}_{2}}-{{y}_{1}})}^{2}}}\] \[=\sqrt{{{(36-0)}^{2}}+{{(15-0)}^{2}}}\] \[=\sqrt{1296+225}=\sqrt{1521}=39\] Since, the position of towns A and B are given (0, 0) (36, 15), respectively and so, the distance between is 38 km.You need to login to perform this action.
