The Old Babylonians didn't really think about right triangles like we do. They thought about the diagonal of a rectangle, which is essentially the same thing. We get the Pythagorean theorem with the sides of the rectangle the legs and the diagonal of the rectangle is the hypotenuse. In our case diagonal d satisfies
d² = 6² + 7² = 36 + 49 = 85
d = √85
d ≈ 9.219
Answer: 9.2
