A rectangular room is shown on a blueprint as 5 inches long and 3 inches wide. The blueprint uses a scale where 1 inch equals 20 feet. It costs $⁢2 per square foot to install new flooring in the room. What is the total cost to install the flooring?

At the scale of 1 inch = 20 feet, the room measures 5 × 20 = 100 feet long and 3 × 20 = 60 feet wide. Its area is 100 × 60 = 6,000 square feet. Flooring costs $2 per square foot, so the total is 6,000 × $2 = $12,000, which is choice D.
