# If a and B Are the Points (−6, 7) and (−1, −5) Respectively, Then the Distance 2ab is Equal to - Mathematics

MCQ

If A and B are the points (−6, 7) and (−1, −5) respectively, then the distance

2AB is equal to

• A. 13

• B. 26

• C. 169

• D. 238

#### Solution

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

therefore AB=sqrt((-6-(-1))^2+(7-(-5))2)

=sqrt((-6+1)^2+(7+5)^2)

=sqrt((-5)^2+(12)^2)

=sqrt(25+144)

=sqrt169

=13

therefore 2AB=2xx13=26

Thus, the distance 2AB is 26 units.
