Step-by-step explanation
Step 1
you can watch that Y-coordinate for A and B is 0, it means both are in the same horizontal line, Y-coordinate for C and D is -1, it means both are in the same horizontal line, so, we have a rectangle
Step 2
fine the base and the height
![\begin{gathered} \text{base= distance from D to C, or distane from A to B} \\ DC=AB=\sqrt[]{(10-7)^2+(0)^2} \\ DC=AB=\sqrt[]{9=3} \\ \text{base}=3 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/ru84l35o1p46ouvwqyy3m73tho4ppktnig.png)
b) height
![\begin{gathered} \text{hegith}=\text{ distance fromA to D , or distance from B to C} \\ AD=\sqrt[]{(-1-0)^2}+(7-7) \\ AD=\sqrt[]{1} \\ AD=1 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/6syurdrku9k33l4rknoxdfe08d2bvr244h.png)
Step 3
finally, the area is
