.
Step-by-step explanation:
We are given with side lengths of a rectangle are (2x-4) units and (x+1) units. It is required to find the area of rectangle.
The area of a rectangle is equal to the product of its length and breadth. It is given by :

Let us consider, L = (2x-4) units and B = (x+1) units
Plugging the side lengths in above formula:

.
Ok so we know that the distance around the circle (or circumference) is equal to the diameter times pi.
This means that

d being the diameter,
This means that:

= 12.00028271
= 12 m
So the diameter of the circle is 12 metres.
Hope this helped
