ANSWER


34 {units}^(2)

Step-by-step explanation

The width of the rectangle is |AB|

A(-1,4) and B(3,3)

We use the distance formula,


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

This implies that,.


d = \sqrt{ {(3- - 1)}^(2) + {(3 - 4)}^(2) }


d = \sqrt{ {(4)}^(2) + {( - 1)}^(2) }


d = √( 16+ 1 )


d = √(17)

The length is BC

C(1,-5) and B(3,3)


d = \sqrt{ {(3- 1)}^(2) + {(3 - - 5)}^(2) }


d = \sqrt{ {2}^(2) + {(8)}^(2) }


d = √(4 + 64 )


d = √(68)


d = 2 √(17)

The area is


= l * w


= 2 √(17) * √(17)


2 * 17 = 34 {units}^(2)
