Answer:

construction a rhombus ABCD in which diagonals are AC and BD

Step-by-step explanation:

At AC

(3,0)(-1,4)

apply distance formula =

√(X2-x1) + (Y2-y1)

(4)2 + (4)2

16+16

4√2

.

AT BD

.(-2,-11)(4,5)

apply formula

we get :- 6√2

multiply AC AND BD

48

Answer:

ac =  \sqrt{  {(x2 - x1)}^{2}  +  {(y2 - y1)}^{2} }

  = \sqrt{ {( - 1 - 3)}^{2} +  {(4 - 0)}^{2}  }

  = \sqrt{ { - 4}^{2}  +  {4}^{2} }

  = \sqrt{16 + 16}

 =  \sqrt{32}

 = 4 \sqrt{2}

bd =  \sqrt{ {(x2 - x1)}^{2}  +  {(y2 - y1)}^{2} }

 = 4 \sqrt{2 \times 6 \sqrt{2} }

 = 4 \sqrt{2}  \times 6 \sqrt{2}

 = 4 \sqrt{2}  \times 6 \sqrt{2}

  =  \sqrt{ {( - 2 - 4)}^{2} + {( - 1 - 5)}^{2}   }

 =  \sqrt{ { - 6}^{2} +   { - 6}^{2}  }

  = \sqrt{36 + 36}

  = \sqrt{72}

 = 6 \sqrt{2}

area \: of \: rombus = d1d2

 = ac \times bd

4 \sqrt{2}  \times 6 \sqrt{2 }  = 48
