Question

WAP to input 3 sides of triangle and find area of the triangle.......plz plz photo bhej ke smjhana​

Answer 1

$\large\mathsf\color{pink}{Solution\: using\: python\: 3}$

def area_of_triangle(a, b, c):

# semi perimeter

sp = (a + b + c) / 2

return (sp * (sp - a) * (sp - b) * (sp - c)) ** 0.5

a, b, c = [float(n) for n in input("enter a b c: ").split()]

print(f"area of traingle is: {area_of_triangle(a, b, c):.2f}")

Answer 2

Answer:

Before writing the program you must understand who the program is supposed to work.

For that write algorithms first,

Step 1: You have to accept 3 inputs of side length of same unit.

Since you have to use sides to find area we're gonna use Heron's Formula.

Step 2:  Use the 3 input sides to find semi perimeter and store the value in a variable

Step 3: As the next steps goes you will need to find square root of products of some numbers as per the formula and for that you need to import a math module just for the sake of keeping things simple and easy.

Step 4: Store a value of area in a variable.

Step 5: Print it on the screen.

Working according to the algorithm we have the following code:

__________________________

#Area of triangle using Heron's formula:

import math

a=int(input("Enter a side length (m): "))

b=int(input("Enter another side length (m) : "))

c=int(input("Enter last side length (m) : "))

sp= (a+b+c)/2

area=math.sqrt(sp*(sp-a)*(sp-b)*(sp-c))

print("The area will be ", area, "meter squared")

I attached an image and a test code to verify this have a look.

You can yourself find area of a 3m, 4m and 5m (Pythagorean triangle)  sided triangle with  1/2*length*breath so it'll be easier to verify.
