The **perimeter** of a rectangle is the total length of all its sides. These sides are the length and width (also known as breadth). The **length** is the longest side, and the shortest side is the **width**.

2(length + width)

Syntax for perimeter

: This represents the length of the rectangle, which is the longest side.**length**

: This represents the shortest side, the width.**width**

The value returned is a float value which is the total length of all the sides of the triangle.

class HelloWorld { public static void main( String args[] ) { // create some lengths float len1 = 3.4F; float len2 = 30; float len3 = 45; float len4 = 100; // create some widths float width1 = 1.2F; float width2 = 4; float width3 = 9.0F; float width4 = 0.2F; // get the perimeters float peri1 = 2 *(len1 * width1); float peri2 = 2 *(len2 * width2); float peri3 = 2 *(len3 * width3); float peri4 = 2 *(len4 * width4); // print the perimeters System.out.println("The perimeter of "+len1+" and "+width1+" is = "+peri1); System.out.println("The perimeter of "+len2+" and "+width2+" is = "+peri2); System.out.println("The perimeter of "+len3+" and "+width3+" is = "+peri3); System.out.println("The perimeter of "+len4+" and "+width4+" is = "+peri4); } }

Getting the perimeter of a rectangle in Java

- Lines 4–7: We create some lengths for the rectangles.
- Lines 10–13: We create the widths as well.
- Lines 16–19: We get the perimeters of the rectangles with the lengths and widths that we created.
- Lines 22–25: We print the perimeters to the console.
