To determine the actual length of the room, you need to use the scale to convert the measurement from the blueprint to real-life dimensions.
According to the given scale, 2 inches on the blueprint represents 5 feet in real life. Therefore, you need to set up the following proportion:
2 inches / 5 feet = 7.5 inches / x
To solve for x (the actual length of the room), cross multiply and divide:
2 inches * x = 5 feet * 7.5 inches
2x = 37.5
x = 37.5 / 2
x = 18.75
Therefore, the actual length of the room is 18.75 feet.
