So basically You have to find out what 10 feet is (2.5) and then divide 2.5 by 10. Next, multiply the answer by 2. So you should get 0.5 inches. Add 2.5 and 0.5 together you get 3. Next you have to find what 26 feet would be using the scale. So you have to Multiply 2.5 bye 2 to get 5 so 5 inches is 20 feet. Next divide 2.5 by 10 then multiply it by 6 to get 1.5 next add 5 and 1.5 to get 6.5.
The answer to the problem is 3 inches by 6.5 inches.
I hope this help :)
