Toby is making a model of a battlefield. The actual area is 11 miles by 7.5 miles. He wants to put the model on a 3.25 ft by 3.25 ft square table with at least 3 inches on each side between the model and table edges. What is the largest scale he can use?

3.25 feet = 39 inches

39 - 6 = 33 inches

11/33 = 3 inches for 1 mile
Multiply 11 by 7.5 which is 82.5. Next multiply 3.25 by 3.25. Now multiply 12 by 1056.25.
1foot : 4 miles
