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......PLEASE ANSWER PROPERLY ONLY IF YOU KNOW HOW TO ANSWER IT CORRECTLY AND PROPERLY..THANK U..IF I LIKE THE ANSWER.I WILL MARK AS BRAINLIEST

Answer 1

Answer:

If a, b and c are three sides of a triangle. Then,

s = (a+b+c)/2

area = √(s(s-a)*(s-b)*(s-c))

Source Code

# 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)

Run Code

Output

The area of the triangle is 14.70

In this program, area of the triangle is calculated when three sides are given using Heron's formula.

If you need to calculate area of a triangle depending upon the input from the user, input() function can be used.
