Answer:
The area of the rectangle is;

Step-by-step explanation:
Given the rectangle LKMN with the coordinates;

Recall that the area of a rectangle is the product of length and width;

From the given coordinates, the length and width of the rectangle are;
![\begin{gathered} w=\sqrt[]{(8-1)^2+(1-1)^2} \\ w=7 \\ l=\sqrt[]{(8-8)^2+(14-1)^2} \\ l=13 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/akfm9vfq6gzl1ekz3ncubfqbjcvqod84d2.png)
Substituting the values of the length and width, we have;

Therefore, the area of the rectangle is;
