R Program to Calculate the Area of a Triangle️‍🔥

In this article, we will discuss how to calculate the Area of a Triangle with its working example in the R programming language. Calculating the area of a triangle is a fundamental geometric task. The area of a triangle can be computed using the base and height of the triangle or by using the lengths of its sides and the semi-perimeter. In this R program, we will explore how to calculate the area of a triangle using the base and height methods.

Syntax:

# Calculate the area of the triangle
area <- 0.5 * base * height
# Print the result
cat("The area of the triangle is:", area)

Example 1:

R

# Values for base and height
base <- 10
height <- 5
 
# Calculate the area of the triangle
area <- 0.5 * base * height
 
# Print the result
cat("The area of the triangle is:", area)

Output:

The area of the triangle is: 25

Assigns the value 10 to the variable base, representing the length of the base of the triangle.
Assigns the value 5 to the variable height, representing the height of the triangle.
Calculates the area of the triangle using the formula 0.5 * base * height and stores the result in the variable area.
Uses the cat() function to print the message.

Example 2:

R

# Values for base and height
base <- 10
height <- 10
 
# Calculate the area of the triangle
area <- 0.5 * base * height
 
# Print the result
cat("The area of the triangle is:", area)

Output:

The area of the triangle is: 50

Assigns the value 10 to the variable base, representing the length of the base of the triangle.
Assigns the value 10 to the variable height, representing the height of the triangle.
Calculates the area of the triangle using the formula 0.5 * base * height and stores the result in the variable area.
Uses the cat() function to print the message.

Example 3: R Program to Calculate the Area of a Triangle using Side Lengths

R

# Function to calculate the area of a triangle using side lengths
calculateTriangleArea <- function(a, b, c) {
  s <- (a + b + c) / 2
  area <- sqrt(s * (s - a) * (s - b) * (s - c))
  return(area)
}
 
# Input: Lengths of the three sides of the triangle
a <- 5
b <- 5
c <- 5
 
# Calculate the area using the function
triangleArea <- calculateTriangleArea(a, b, c)
 
# Display the result
cat("\nThe area of the triangle with side lengths", a, b, c, "is:", triangleArea, "\n")

Output:

The area of the triangle with side lengths 5 5 5 is: 10.82532

Define a function named calculateTriangleArea that takes three parameters a, b, and c.
Inside the function, calculate the semi-perimeter s of the triangle by adding a, b, and c and then dividing by 2.
Calculate the area of the triangle using the formula for the area of a triangle given its side lengths: area = sqrt(s * (s – a) * (s – b) * (s – c)).
Return the calculated area from the function.
Assign the value 5 to variables a, b, and c, representing the side lengths of the triangle.
Call the calculateTriangleArea function with the side lengths a, b, and c as arguments. The calculated area is returned and stored in the variable triangleArea.
Display a message using cat, indicating the area of the triangle with side lengths a, b, and c, and showing the calculated triangleArea.
