Answer :
8√2 u ²
1) Since, we've been given those points let's find their distances through this formula below, derived from the Pythagorean Theorem:
Side GH:
[tex]\begin{gathered} d_{GH}=\sqrt[]{(x_2-x_1)^2+(y_2-y_1)^2\text{ }}_{} \\ d_{GH}=\sqrt[]{(-2_{}+4_{})^2+(4-2)^2\text{ }} \\ d_{GH}=2\sqrt[]{2} \\ \\ \\ \\ \end{gathered}[/tex]2) Plotting the graph and using the side GH as the base and tracing a height 8 units plugging into the formula for the area
