If A(-6,7) and B(-1,-5) are two given points then the distance 2AB is (a) 13 (b) 26 (c) 169 (d) 238

Answer»

Correct answer is (b) 26

The given points are A(-6,7) and B(-1,-5). So

AB = \(\sqrt{(-6+1)^2+(7+5)^2}\)

\(\sqrt{(-5)^2+(12)^2}\)

\(\sqrt{25+144}\)

\(\sqrt{169}\)

= 13

Thus, 2AB = 26.
