Answer:
The answer to your question is 74 u²
Explanation:
Process
1.- Find the 4 vertices
A (-2, 8)
B (0, -4)
C (4, 9)
D (6, -3)
2.- Find the length of the base and the height

Distance AB = \sqrt{(0 + 2)^{2} + (-4 - 8)^{2} }[/tex]
dAB =

dAB =

Distance BD = \sqrt{(6 - 0)^{2} + (-3 + 4)^{2} }[/tex]
dBD =

dBD =

3.- Find the area
Area = base x height
Area =

Area =

Area = 74 u²
