Ratio compares two things. The length of the trail, in reality, is 6.75 km.
<h3>What is the scale ratio?</h3>
A scaling ratio helps us to compare two things.
Given to us
The scale on the map states that 2 centimeters represent 3 kilometers.
Length of the trail on the map, L = 4.5 cm = 0.045 m
As we know that 2 centimeters represent 3 kilometers. therefore,
We know that the Length of the trail on the map is 0.045 m,
Substitute the value,
Hence, the length of the trail, in reality, is 6.75 km.

Answer:
Step-by-step explanation:
An = 54 + 3(n-1)
n = 1 ; A1 = 54 + 3*(1-1) = 54 + 3*0 = 54 +0 = 54
n =2 ; A2 = 54 + 3*(2-1) = 54 + 3*1 = 54 + 3 = 57
n =3 ; A3 = 54 + 3*(3-1) = 54 + 3*2 = 54 + 6 = 60
n =4 ; A4 = 54 + 3*(4-1) = 54 + 3*3 = 54 + 9 = 63
