Question

Work out the length of AB.
Give your answer to 3 significant figures.
A=(-1,6) B=(5,3)

Answer 1

D = 6.71

Explanation:

For Finding Length, we'll use the distance Formula:

=> Distance Formula =
`√((x2-x1)^2+(y2-y1)^2)`

=> D =
`√((5+1)^2+(3-6)^2)`

D =
`√(6^2+(-3)^2)`

D =
`√(36+9)`

D =
`√(45)`

D = 6.71

The length of AB is 6.71
