Answer
the distance between the unwelded ends is $c = 10.8ft$
Work Step by Step
The distance between the two unwelded ends (we can call it $c$) is the hypotenuse of the right triangle formed.
We have the sides:
$a=6ft$
$b=9ft$
So, by using the Pythagorean Theorem, we get:
$c^2=a^2+b^2$
$c^2=6^2+9^2$
$c = \sqrt {(6ft)^{2} + (9ft)^{2}} = 10.82ft\approx10.8~ft$
