Question

The distance Ab round to the nearest tenth?

Answer 1

Coordinates of point A is (-2 and 1)

Coordinates of point B is (1 and -1)

`\begin{cases}\large\bf\red{ \longrightarrow} \rm \: Distance \: = \: √((x_2 - x_1 ) \: + \:(y_2 - y_1 )) \\ \\ \large\bf\red{ \longrightarrow} \rm \:Distance \: = \:\sqrt{(1 - [ - 2]) ^(2) \: + \:( - 1 - 1)^(2) } \\ \\ \large\bf\red{ \longrightarrow} \rm \: Distance \: = \: \sqrt{( - 3) ^(2) \: + \:( - 2) ^(2)} \\ \\ \large\bf\red{ \longrightarrow} \rm \: Distance \: = \: √(6 \: + \: 4) \\ \\ \large\bf\red{ \longrightarrow} \rm \: Distance \: = \: √(10) \ \\ \ \\ \large\bf\red{ \longrightarrow} \rm \: Distance \: = \:3.1622 \: \: units \end{cases}`
