Answer:
feet
Explanation:
We will use the Pythagorean Theorem to solve this. Which states that:
One Length^2 + Another Length^2 = Hypotenuse^2
We can take one length as 5 ft and another length as 9 ft and we call the hypotenuse "h", so we have:
![5^2+9^2=h^2](https://img.qammunity.org/2021/formulas/mathematics/middle-school/alnwdwa5jamm3whs8mus2gjunfx8us4lyy.png)
Now, let us solve for "h":
![5^2+9^2=h^2\\25 + 81 = h^2\\106=h^2\\h=√(106) \approx 10.3](https://img.qammunity.org/2021/formulas/mathematics/middle-school/pzcx330j8htozqu7ukqer2583gb7kad8af.png)
The pond's hypotenuse is about 10.3 feet
