You're almost there. You are dealing with ratios. Every half inch represents 25 feet. Your two geographic dimensions are 500 feet by 400 feet. How many times is 25 feet (for the half inch on the drawing) contained in 500, and 400 feet, each? Now, how many half inch lengths in both directions does your drawing need?
