Question

Write a python program for the following: i)To calculate the area of a circle, a rectangle, or a triangle depending upon the user's choice with inputs according to the choice given by the user. ii)To input 3 numbers and calculate two sums as per the conditions below: a)For two even numbers, b)For two odd numbers and c)For numbers which are ending with 7

Answer 1

Answer:

# Python Program to find the area of triangle

a = 5

b = 6

c = 7

# Uncomment below to take inputs from the user

# a = float(input('Enter first side: '))

# b = float(input('Enter second side: '))

# c = float(input('Enter third side: '))

# calculate the semi-perimeter

s = (a + b + c) / 2

# calculate the area

area = (s*(s-a)*(s-b)*(s-c)) ** 0.5

print('The area of the triangle is %0.2f' %area)
