Question

if A and B are points (-6,7) and (-1,5) respectively. find distance 2AB

Answer 1

Distance = √[(-6-1)²+ (7-5)²]

= √(53)

= 7.2 = AB

2AB = 2 × 7.2 = 14.4 units

Answer 2

$x1 = - 6 \: \: \\ x2 = - 1 \\ y1 = 7 \: and \\ y2 = 5 \\ then$
√ (X2 - X1 )^2 + (Y2 - Y1 )^2 = AB
√(6 - 1)^2 + (7 - 5)^2
√25 + 4
√ 29
