Answer:
Answer D
Step-by-step explanation:
1/2 in. = 25 mi.
1 in. = 50 mi.
12x50 = 600
12 represents the total inches on the map to her friends town 50 represents the miles an inch.
So before we can find the perimeter, we need to find the hypotenuse. Since this is a right triangle, we can use the pythagorean theorem. The equation for that is
, in which a and b are the legs of the triangle and c is the hypotenuse.
With this info, we can form our equation: 
Firstly, solve the exponents: 
Next, combine everything on the left side: 
Next, square root both sides, and your hypotenuse will be 15 = c.
Now that we have all the triangle side lengths, just add everything up: 
In short, the perimeter is 36 inches.
