Answer:
453.75 sq. feet
Step-by-step explanation:
In this question, we are going to calculate the area of a room given the blue print measurement and the actual measurements with the answer being in the actual measurement.
To correctly do this, it is best if the measurements are converted to the actual.
The measurements we’ll be trying to convert is 5 inches by 3 inches with a scale of 2in to 11ft ( same as 1 in to 5.5 ft)
The 5 inches blueprint measurement will be 5 * 5.5 = 27.5 ft
The 3 inches blueprint measurement will be 3 * 5.5 = 16.5 ft
The area in sq. feet will be length * width = 27.5 * 16.5 = 453.75 sq feet
