Answer:
The perimeter of the Rectangle JKLM is 32 unit.
Step-by-step explanation:
Consider the provided coordinates.
Rectangle JKLM: J(-3, 8), K(-3,-1), L(4, -1), M(4,8)
First plot the points as shown in figure:
The required figure is shown below:
Now find the distance between JK by using the distance formula.


Therefore, the length of JK is 9 unit.
Now find the length of the side JM

Therefore, the length of JM is 7 unit.
The perimeter of rectangle is: 
Therefore,



Hence, the perimeter of the Rectangle JKLM is 32 unit.
