Consider a right triangle where one leg measures 4 units and the other leg measures 3 units. To find the length of the hypotenuse, you can use the Pythagorean theorem:
$$c = \sqrt{a^2 + b^2}$$
where $a$ and $b$ are the lengths of the legs of the triangle, and $c$ is the length of the hypotenuse. Using the lengths provided, what is the length of the hypotenuse?
