Objective

In this challenge, we practice creating objects. Check out the attached tutorial for more details.

Task

Complete the function in the editor. It has two parameters:  and . It must return an object modeling a rectangle that has the following properties:

• : This value is equal to .
• : This value is equal to .
• : This value is equal to 
• : This value is equal to 

Note: The names of the object's properties must be spelled correctly to pass this challenge.

Input Format

The first line contains an integer denoting .
The second line contains an integer denoting .

Constraints

Output Format

Return a object that has the properties specified above. Locked code in the editor prints the returned object's , , , and  to STDOUT.
