**How do you find the area of a rectangle in Java?**

The area of a rectangle is the amount of space obtained by the rectangle. A rectangle can be defined as a plane shape that has two adjacent sides of length. The 4 angles present in the rectangle are also equal. A rectangle can be divided into 4 equal squares. Each internal angle in a rectangle measures 90 degrees.

The area of a rectangle is the number of square units to fill a rectangle completely.

### Algorithm to find the Area of Rectangle

step -1: start.

step -2: import the package

step -3: Create class Area.

step -4: create the main() function

step -5: Create object Scanner obj=new Scanner(String[]args)

step -6: create the integer variable l,h

step -7: create the user input as leangth=obj.nextInt();

step -8: create the user input as height=obj.nextInt();

step -9: Calculate the area of Rectange area=length*height.

step -10: print the output of area.

step -11: end.

### Area of a Rectangle in Java With Source Code:

import java.io.*; import java.util.*; public class Rectangle { public static void main(String []args) { Scanner ob=new Scanner(System.in); int l,h; System.out.println("Enter lenght of Rectangle: "); l=ob.nextInt(); System.out.println("Enter height of Rectangle: "); h=ob.nextInt(); int Rec=l*h; System.out.println("Area of rectangle is: "+Rec); } }
