Answer:
The length in centimeters of the Panama Canal on Ana’s map is 16.4 cm
Explanation:
we are given that
Ana drew a map of the Panama Canal. In the scale Ana used for the map, 4 centimeters represents 20 kilometers
so,
20 km =4 cm
now, we can find 1 km
we can divide both sides by 20

now, we can multiply both sides by 82

now, we can simplify it
we get
82 km =16.4 cm
So,
The length in centimeters of the Panama Canal on Ana’s map is 16.4 cm
