Darell made a scale drawing of a shopping center. The parking lot is 4 centimeters wide in the drawing. The actual parking lot is 40 meters wide. What scale did Darell use?
1 centimeter : meters
To find the scale, we need to determine how many centimeters represent one meter in the drawing.
If the parking lot is 4 centimeters wide in the drawing and the actual parking lot is 40 meters wide, we can set up a ratio:
4 centimeters : 40 meters
To simplify this ratio, we divide both sides by the greatest common divisor, which is 4:
1 centimeter : 10 meters
Therefore, Darell used a scale of 1 centimeter : 10 meters.
