What is the perimeter of this triangle ⬆️

40 meters.

Step-by-step explanation:

According to the Pythagorean Theorem, a squared plus b squared equals c squared, where c is the hypotenuse. You then have 64+225, or 290 equals c squared. Find the square root of 290, which is about 17 when rounded to the nearest tenth. Thus, add 17, 8, and 15 to get 40 meters.
