Remember that the area of a rectangle is width * height: static int getArea(Rectangle r) { return r.width * r.height; }

Write a program that calculates the area of a triangle in QBASIC
We can use any method. As we can find out the area of the circle by three methods as i known. 1.ordinary programming e.g. void main() { int r;float area; printf("\n\tEnter radius of the circle : "); scanf("%d",&r); area=3.14*r*r; printf("Radius = %d and area=%f",r,area); } 2. By using macros e.g. #define PI 3.14 #define AREA(x) PI*x*x 3. We can solve by user defined functions also

1. Start 2. Input the the value of radius R 3. Let PI=3.14 4. Calculate area=PI*R*R 5. Print area 6.End
Area of any triangle: 0.5*base*perpendicular height

To calculate the area of a rectangle, you can use the following algorithm: Input the length (L) and width (W) of the rectangle. Compute the area using the formula: Area = Length × Width. Output the calculated area. For example, if L = 5 units and W = 3 units, the area would be 5 × 3 = 15 square units.
Rewrite the above program so that the program accepts any value for the radius then recalculate the area of the circle.
Find the radiusMultiply pi by the square of the radius.
In which computer language?
Pi can be used to calculate the area of a circle Pi can be used to calculate the circumference of a circle
To calculate the area of a circle, you can use the formula A = πr^2, where A is the area and r is the radius of the circle. Simply square the radius, multiply it by π (approximately 3.14159), and you will have the area of the circle.
To calculate the area of a circle use this formula: pi x r2.
