A Right triangle is a triangle that has an angle whose measure is 90 degrees.
A 45°-45°-90°-degree triangle is a Right triangle that has two angles that measure 45 degrees. This triangle has two sides of equal length.
You can identify that the triangle given in the exercise is a 45°-45°-90°-degree triangle.
According to the 45°-45°-90° Triangle theorem:
In this case:
Substituting values into the equation and evaluating, you get that length of the path will be the following:
The answer is:
