Answer:

  • 3.6

Explanation:

A = ( -2, 1 )

B = ( 1, -1 )


\boxed{\bf x_1 : - 2}
\boxed{\bf x_2 : 1}


\boxed{\bf y_1 : 1}
\boxed{\bf y_2 : - 1}

______________________________


  • \sf d = \sqrt{(x_2 -x_1) ^(2) + ( y_2 - y_1) ^(2) }

  • \sf d = \sqrt{(1 - ( - 2)) ^(2) + ( - 1 - 1) ^(2) }

  • \sf d = \sqrt{ {3}^(2) + {( - 2)}^(2) }

  • \sf d = √((9 + 4))

  • \sf d = √(13)

  • \sf d = 3.6
