(05.01)A scale drawing of a bathroom is shown below: A rectangle is shown. The length of the rectangle is labeled 2 inches. The
width of the rectangle is labeled 3.5 inches. The scale is 1 to 20. What is the area of the actual bathroom in square feet? Round your answer to the nearest whole number. 7 ft^2 19 ft^2 12 ft^2 140 ft^2
2 by 3.5 is the area for the model. Every 1 is meant to represent 20, so multiply both 2 and 3.5 by 20. 2 * 20 = 40 3.5 * 20 = 70 40 * 70 = 2800 in^2 Every 12 inches is 1 foot so divide 2800 by 12^2 (one square foot), or 144. 2800/144 = 19.44444 Round down because .4 is less than half. Approximately 19 ft^2
