To calculate the perimeter of the actual room, we need to convert the measurements from inches to feet using the given scale of 2.5in : 35ft.
First, let's calculate the length of the room in feet:
Length of the room in feet = (Length on the drawing / Scale) = (8in / 2.5in) * 35ft = (8/2.5) * 35ft = 11.2ft
Next, let's calculate the width of the room in feet:
Width of the room in feet = (Width on the drawing / Scale) = (6in / 2.5in) * 35ft = (6/2.5) * 35ft = 84ft
Now, we can calculate the perimeter of the actual room:
Perimeter of the room = 2 * (Length of the room + Width of the room) = 2 * (11.2ft + 84ft) = 2 * 95.2ft = 190.4ft
Therefore, the perimeter of the actual room is 190.4 feet.
