hello, to solve your answer, we need to put this points in the cartesian plane:
Now, look at the image:
- 3 units in lenght and 7 units in height.
So, we can calculate the area multiplying the measurements of the sides.Look:
[tex]\begin{gathered} \text{Area = lenght }\times\text{ height} \\ \text{Area = 7 }\times\text{ 3} \\ \text{Area = 21 units} \end{gathered}[/tex]
