Can anyone help. Greatly appreciate:)

Answer:

Area= 12 units squared, Perimeter= 16.12899

Step-by-step explanation:

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

AB= \sqrt{(0-4)^{2}+ (2-0)^{2} } = 2\sqrt{5}

BC= \sqrt{(0-0)^{2}+ (2+4)^{2} }= 6

So, perimeter= 4\sqrt{2} + 2\sqrt{5} +6= 16.12899

Area= \frac{1}{2}bh\\

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

         = 12 units^{2}
