On the scale drawing of a floor, plan A room is 7 in. long on the scale drawing. Find the actual length of the room.
What is the scale?
'
To find the actual length of the room, we need to know the scale factor of the scale drawing, which represents the relationship between the measurements on the drawing and the actual measurements.
For example, if the scale on the drawing is 1 inch = 10 feet, it means that 1 inch on the drawing represents 10 feet in actuality.
Assuming we have the scale factor, we can use it to find the actual length of the room. In this case, the scale factor is not provided, but we can make a general example using a scale factor of 1 inch = 1 foot.
If the room is 7 inches long on the scale drawing, we can multiply it by the scale factor to find the actual length:
Actual length of the room = Length on the scale drawing * Scale factor
Actual length of the room = 7 inches * 1 foot/inch
Actual length = 7 feet
So, in this case, the actual length of the room would be 7 feet.
However, without the specific scale factor provided for the drawing, we cannot determine the actual length accurately.
