Please help me with the task: Draw a way to a safe place.

Hello, I’m working on this task:

Write a program that calculates and outputs to the screen the distance from your position (blue dot) to the destination (red dot). Tip: You need to use int variables and plus ‘+’ operation in your solution.

Here is my code:

using System;

public static class DrawToSafetyPlace
   public static void Main()
       int result = 175+175;

Can anyone please help me to solve it?
