The drawing of the lake has the scale of 1 centimeter to 80 meters.
Now, the actual width of the scale is of 1000 meters.
To find out the width of the lake on the drawing we need to convert the actual length as per the scale drawing.
Since we know that in the given scale drawing we have,
1 centimeter = 80 meters
Or we can say that
80 meters = 1 centimeter
1 meter = meter
Now, 1000 meters should be equivalent to
centimeters.
Therefore, the width of the lake on the scale drawing is 12.5 centimeters.
