Java Program to Find the Perimeter of a Circle, Rectangle and Triangle

In this program, you will learn to Find the Perimeter of a Circle, Rectangle and Triangle in Java.

Formula:

Perimeter of circle = 2*pi*r
Perimeter of rectangle = 2*(l+b)
Perimeter of triangle = (s1+s2+s3)

Enter the radius of the circle, length and breadth of the rectangle and three sides of the triangle as inputs. Calculate the perimeter by using formula and get the desired output.
