Final answer:
The width of the rectangular room, when converted from the blueprint to actual dimensions using the scale of 1 inch to 72 feet, is 144 feet.
Step-by-step explanation:
The student is asking about converting the width of a rectangular room from a blueprint into actual dimensions. The blueprint uses a scale where 1 inch represents 72 feet. To find the width of the room in feet, we use a simple proportion where the unit scale is equal to the actual scale.
Given that the width on the blueprint is 2 inches, we have the proportion:
Width (actual) / Width (blueprint) = Scale ratio (feet/inch)
w / 2 inches = 72 feet / 1 inch
Cross-multiplying gives us:
w × 1 inch = 2 inches × 72 feet
w = 144 feet
Therefore, the width of the real room is 144 feet.
