Write a C program to input base and height of a triangle and find area of the given triangle. How to find area of a triangle whose base and height is given by user in C programming. C program to calculate area of a triangle if base and height of the triangle are given. Logic to find area of a triangle in C program.

**Example**

**Input**

Enter base of the triangle: 10 Enter height of the triangle: 15

**Output**

Area of the triangle = 75 sq. units

## Required knowledge

Fundamentals of C, Data types, Talking user input in C

## Area of triangle

Area of a triangle is given by the formula -

## Logic to find area of a triangle

Area of a triangle can be calculated easily if its base and height are given. Below is the step by step descriptive logic to find area of a triangle -

- Input base of the triangle in some variable say base.
- Input height of the triangle in some variable say height.
- Apply the formula to calculate area i.e. area = (base * height) / 2.
- Print the resultant value of area.

## Program to find area of triangle

/** * C program to find area of a triangle if base and height are given */ #include <stdio.h> int main() { float base, height, area; // Input base and height of the triangle printf("Enter base of the triangle: "); scanf("%f", &base); printf("Enter height of the triangle: "); scanf("%f", &height); // Calculate area of the triangle area = (base * height) / 2; // Print the resultant area printf("Area of the triangle = %.2f sq. units", area); return 0; }

**Note:** %.2f is used to print fractional values only up to 2 decimal places. You can also use %f to print up to 6 decimal places by default.

Enter base of the triangle: 10 Enter height of the triangle: 15 Area of the triangle = 75.00 sq. units

Happy coding ;)
