How do you write a program that calculates the area of a triangle?

C program to find area of a triangle using a function

1. double area_of_triangle(double, double, double);
2. int main()
3. scanf(“%lf%lf%lf”, &a, &b, &c);
4. area = area_of_triangle(a, b, c);
5. printf(“Area of the triangle = %.2lf\n”, area);
6. double area_of_triangle(double a, double b, double c)
7. s = (a+b+c)/2;

How do you make a triangle in JavaScript?

What are two ways to find the area of a triangle?

Here are seven (slightly) different ways to calculate the area of a triangle:

1. Area = a*h/2.
2. Area = a*b*sin(C)/2.
3. Area = a2*sin(B)*sin(C)/(2*sin(B+C))
4. Area = sqrt(s*(s-a)*(s-b)*(s-c))
5. Area = f*g/2 -v*w/2.
6. Area = abs((xB*yA-xA*yB)+(xC*yB-xB*yC)+(xA*yC-xC*yA))/2.

What is the rule of Triangle?

Interior Angles of a Triangle Rule No matter how you position the three sides of the triangle, the total degrees of all interior angles (the three angles inside the triangle) is always 180°. This property of a triangle’s interior angles is simply a specific example of the general rule for any polygon’s interior angles.

How do you get perimeter from area?

To get the perimeter from the area for a square, multiply the square root of the area times 4 . Perimeter is always measured in linear units, which is derived from the area’s square units.

How do you find the perimeter and area of a shape?

Rectangles

1. Rectangles.
2. The perimeter of a rectangle is the sum of its four sides. Since a rectangle has two.
3. perimeter = 2l + 2w.
4. The area of a rectangle is equal to its length times its width.
5. area = l * w.
