Answer:
The actual base length is 4.1 meters
Step-by-step explanation:
The reason why is since the scale is for every 1 inch it represent 2 meters, we know that 2 inches would be 4 meters. Now since there is a half we have to take half of the two meters to see what half an inch would be represented by. Since half of two is one, it is 4.1 meters.
