Answer:
The distance that Peter rides is:
Step-by-step explanation:
To identify the miles that Peter rides, you must imagine the triangle with measures: 3.36 miles, 4.18 miles, and 5.61 miles. How you can suppose, Peter regularly rides exactly by each side of the triangle mentioned, then you must find the perimeter of the triangle to identify the miles that Peter rides, remember that the perimeter of an irregular triangle is:
- Perimeter of a triangle = side + side + side
If you replace the formula, you obtain:
- Perimeter of a triangle = 3.36 miles + 4.18 miles + 5.61 miles
- <u>Perimeter of a triangle = 13.15 miles</u>
 
        
             
        
        
        
Answer:
Option (B)
Step-by-step explanation:
From the figure attached,
ΔBCD and ΔACE are the similar triangles.
Therefore, by the property of similar triangles, corresponding sides of these similar triangles will be proportional.





AB + 6 = 24 
AB = 18
Option (B) will be the answer.
