driven program to calculate perimeter and area of different shapes
all the required functions with the calculations of perimeter of different shapes
def per_circle(radius):
perimeter = 2 * 3.14 * radius

def per_triangle(side1, side2, side3):
perimeter = side1 + side2 + side3

def per_rectangle(height, width):
perimeter = 2 * (height + width)
