Answer: If the length of rectangle is 13 feet , then the breadth of rectangle would be 18-13=5 feet.
If the length of rectangle is 5 feet, then the breadth of rectangle would be 18-5=13 feet.
Step-by-step explanation:
Since we have given that
Perimeter of rectangular region = 36 feet
Area of rectangular region = 65 sq feet
Let the length of rectangle be 'l'.
Let the breadth of rectangle be 'b'.
As we know the formula for perimeter of rectangle :

And area of rectangle = Length × Breadth
so, it becomes

Hence, If the length of rectangle is 13 feet , then the breadth of rectangle would be 18-13=5 feet.
If the length of rectangle is 5 feet, then the breadth of rectangle would be 18-5=13 feet.
