Calculate Area of Trapezoid

You need to know the Breadth 1, Breadth 2, and Height of to Trapezoid to calculate the area.


1. b1 : (Datatype int): to represent the breadth 1 of Trapezoid.

2. b2 : (Datatype int): to represent the breadth 2 of Trapezoid.

3. height : (Datatype long): to represent the height of Trapezoid.

4. area_of_trapezoid: (Datatype long): to store the result of the area of the Trapezoid being computed.


printf(): is used to display something on the console/screen. Format specifier %d in printf function is used to display an int variable on-screen and %ld for long. \n is used to add a new line

scanf(): is used to fetch data inputted by the user on the console/screen using the keyboard. %d in scanf is indicated that inputted text is of type int and %ld for long.


Area of Trapezoid : (height/2) x (b1 + b2);

	printf(" Enter the Height of a Trapezoid : ");
	scanf("%d", &height);
    printf("\n\n Enter the Breadth1 value : ");
	scanf("%d", &b1);
    printf("\n\n Enter the Breadth2 value : ");
    scanf("%d", &b2);

	area_of_trapezoid = (height/2)*(b1+b2);

	printf("\n\n Area of Trapezoid with Height as %d, Breadth1 as %d and Breadth2 as %d = 

//	getch();

Program to calculate Area of a Trapezoid:
Enter the Height of a Trapezoid: 15
Enter the Breadth1 value : 30
Enter the Breadth2 value : 10
Area of Trapezoid with Height as 15, Breadth1 as 30 and Breadth2 as 10 = 280

The best way to learn C programming is to practice more and more programs. Code2care C Programming tutorials provide 1000+ programs in C that you can study and become an expert in the language. Programs are divided into categories depending upon type and complexity.

BSc. IT, BSc. Computer Science, BSc. IT, MSc. IT, MSc. Computer Science, MCA, BTech IT & BTech Engineers may find these programs very useful.
