* C Program to Find the Perimeter of a Circle, Rectangle and Triangle
|
||
|
|
This C Program calculates the perimeter of a circle, rectangle and triangle. This program is used to find the perimeter of a circle, rectangle and triangle. The formula used in this program are
|
||
|
|
perimeter of rectangle: 2 * (a + b)
|
||
|
|
perimeter of General triangle: a + b + c
|
||
|
|
perimeter of Equilateral triangle: 3 * a
|
||
|
|
perimeter of Right angled triangle: width + height + sqrt(width ^ 2 + height ^ 2)
|
||
|
|
perimeter of circle: 2 * pi * r
