Area of an Equilateral Triangle

  • The Equilateral Triangle is a triangle with all sides are equal and all of the angles are equal to 60 degrees.
  • If we know the side of an Equilateral Triangle then, we can calculate the area of an Equilateral Triangle using below formula.
Area = (√3)/4 * s² (S = Any side of the Equilateral Triangle)

  • Perimeter is the distance around the edges. We can calculate perimeter using below formula:
Perimeter = 3s

  • We can calculate Semi Perimeter of an Equilateral Triangle using the formula: 3s/2 or we can simply say Perimeter/2.
  • We can calculate Altitude of an Equilateral Triangle using the formula: (√3)/2 * s

Python Program to find Area of an Equilateral Triangle

  • This program allows the user to enter length of any one side of an Equilateral Triangle.
  • Using this value we will calculate the Area, Perimeter, Semi Perimeter and Altitude of an Equilateral Triangle.

Sample Code

# Python Program to find Area of an Equilateral Triangle
import math
 
side = float(input('Please Enter Length of any side of an Equilateral Triangle: '))
 
# calculate the area
Area = (math.sqrt(3)/ 4)*(side * side)
 
# calculate the Perimeter
Perimeter = 3 * side
 
# calculate the semi-perimeter
Semi = Perimeter / 2
 
# calculate the Altitude
Altitude = (math.sqrt(3)/2)* side
 
print("\n Area of Equilateral Triangle = %.2f" %Area)
print(" Perimeter of Equilateral Triangle = %.2f" %Perimeter)
print(" Semi Perimeter of Equilateral Triangle = %.2f" %Semi)
print(" Altitude of Equilateral Triangle = %.2f" %Altitude)

Python Program to find Area of an Equilateral Triangle using functions

  • This program allows the user to enter length of any one side of an Equilateral Triangle.
  • We will pass that value to the function arguments to calculate the area of an equilateral triangle.

Sample Code

# Python Program to find Area of an Equilateral Triangle using Functions
import math
 
def Area_of_an_Equilateral_Triangle(side):
    # calculate the area
    Area = (math.sqrt(3)/ 4)*(side * side)
    
    # calculate the Perimeter
    Perimeter = 3 * side
 
    # calculate the semi-perimeter
    Semi = Perimeter / 2
 
    # calculate the Altitude
    Altitude = (math.sqrt(3)/2)* side
 
    print("\n Area of Equilateral Triangle = %.2f" %Area)
    print(" Perimeter of Equilateral Triangle = %.2f" %Perimeter)
    print(" Semi Perimeter of Equilateral Triangle = %.2f" %Semi)
    print(" Altitude of Equilateral Triangle = %.2f" %Altitude)

Analysis

  • First, We defined the function with one argument using def keyword.
  • It means, User will enter any one side of an equilateral triangle.
  • Next, We are Calculating the an equilateral triangle as we described in our first example.
