This rules out two as it is 1 foot short.
3 is also ruled out as there would be no dimension to the flower bed - it would be impossible to make a triangle.
Now do the reverse - use on of the remaining logs to test if they would work.

9 + 6 = 15 > 13 feet
The only log it can be is C 13 feet.

Step-by-step explanation:
Planes always intersect in a line.
If Nate paints the wall in 4 hours, it means that he can paint 1/4 of the wall every hour.
Similarly, if Jill paints the wall in 7 hours, it means that he can paint 1/7 of the wall in one hour.
So, together, they paint the following fraction of the wall in one hour:
.
At this rate, they need 28/11 hours to paint the whole wall, in fact, after that amount of time they paint
i.e. the whole wall
