Final answer:
The actual area of the master bedroom in real life is 40 sq ft.
Step-by-step explanation:
To find the actual area of the master bedroom in real life, we need to use the given scale on the blue print. The scale is 1/4 in = 2 ft, which means every 1/4 inch on the blue print represents 2 feet in real life.
The master bedroom is 2 1/2 in by 4 in on the blue print. To find the actual dimensions, we can multiply the dimensions on the blue print by the scale factor.
2 1/2 in * 2 ft/in = 5 ft, and 4 in * 2 ft/in = 8 ft. Therefore, the actual area of the master bedroom in real life is 5 ft * 8 ft = 40 sq ft.
