Answer:
|AB| = √((7 - (-2))^2 + (-3 - 9)^2) = 15
|BC| = √((-2 - 7)^2 + (-3 - (-3))^2) = 9
|AC| = √((-2 - (-2))^2 + (-3 - 9)^2) = 12
Perimeter = 15 + 9 + 12 = 36

The proportion can be used to find the distance on the map (x) that represents 50 miles will be x/50 = 5 / 200. Then the correct option is A.
<h3>What are ratio and proportion?</h3>
A ratio is a collection of ordered integers a and b represented as a/b, with b never equaling zero. A proportionate expression is one in which two items are equal.
The scale on a map shows that 200 miles is represented by 5 inches on a map.
Then the proportion can be used to find the distance on the map (x) that represents 50 miles will be
x/50 = 5 / 200
Then the correct option is A.
