They are not. Semaphore is a method of sending signals by using flags or lights whereas perimeter is a geometric property of closed shapes!
To avoid deadlocks using semaphores, you need to carefully plan the order in which semaphores are acquired and released in your code. Make sure to always acquire semaphores in the same order to prevent circular dependencies. Additionally, consider using techniques like timeout mechanisms or resource hierarchy to prevent deadlocks.
Search Google with: "Linux semaphores" and have a look through the websites on the subject.
As the use of semaphores in the past has caused more problems than created solutions therefore semaphores are not use in the producer and consumer problem.
Then they both will have the same perimeter
The perimeter of a circle is its circumference.
Circumference is the perimeter of a circle.
it means make same shapes only perimeter
No. For example, a 4x1 rectangle will have an area of 4 and a perimeter of 10. A 2x2 rectangle will have the same area of 4, but a perimeter of 8.
Like condoms.

Any plane shape can have the same perimeter as any other plane shape.
No, two rectangles do not have to be congruent if they have the same perimeter. Rectangles can have the same perimeter while differing in their length and width. For example, a rectangle with dimensions 4x6 has the same perimeter (20 units) as a rectangle with dimensions 5x5, but they are not congruent since their shapes and sizes differ.
