1 ) Write a Java program to calculate the area of a rectangle with a length of 15 cm and a breadth of 10 cm.
Program:
public class RectangleArea {
public static void main(String[] args) {
// Declare and initialize the length and breadth variables
int length = 15;
int breadth = 10;
// Calculate the area of the rectangle
int area = length * breadth;
// Print the result
System.out.println("The area of the rectangle is: " + area + " cm²");
}
}
Output:
The area of the rectangle is: 150 cm²
