Mr. Smith has a scale drawing of his rectangular swimming pool. The lenght is 15" and the height is 11". The scale is 1 inch = 2 feet.
What is the perimeter of the actual pool? Do I add 15 + 15 + 11 + 11 to get the perimeter?

your answer to 15 + 15 + 11 + 11 would still be in inches.
The sum is 52 inches, but each inch is 2 feet.
So the perimeter of the pool would be 104 feet.
