# Java Exercises: Print the area and perimeter of a rectangle

## Java Basic: Exercise-13 with Solution

Write a Java program to print the area and perimeter of a rectangle.

** Java: Perimeter of a rectangle**

A perimeter is a path that surrounds a two-dimensional shape. The word comes from the Greek peri (around) and meter (measure). The perimeter can be used to calculate the length of fence required to surround a yard or garden. Following image represents the perimeter of a rectangle.

**Java: Area of a rectangle**

In Euclidean plane geometry, a rectangle is a quadrilateral with four right angles. To find the area of a rectangle, multiply the length by the width.

A rectangle with four sides of equal length is a square.

Following image represents the area of a rectangle.

**Sample Solution**:

**Java Code:**

```
public class Exercise13 {
public static void main(String[] strings) {
final double width = 5.6;
final double height = 8.5;
double perimeter = 2*(height + width);
double area = width * height;
System.out.printf("Perimeter is 2*(%.1f + %.1f) = %.2f \n", height, width, perimeter);
System.out.printf("Area is %.1f * %.1f = %.2f \n", width, height, area);
}
}
```

Sample Output:

Perimeter is 2*(8.5 + 5.6) = 28.20 Area is 5.6 * 8.5 = 47.60
