Answer:
[tex]\sqrt{250}[/tex]
Step-by-step explanation:
We are given a rectangle PQRS represents the fence around a dog park and Martin's dog runs in a straight line from corner S to corner Q.
We are to find the distance that Martin's dog runs.
Considering the path followed by Martin's dog, we can see that SQR makes a right angled triangle so we can use Pythagoras Theorem to find the distance from S to Q.
Distance Q-R = 9 meters
Distance S-R = 13 meters
Distance that Martin's dog runs = [tex]\sqrt{(12)^2+(9)^2}=\sqrt{250}[/tex]
