AccordingAccording to the floor plan, the one that is closest to the total length, in feet, of the walls that Kamal should quote to the artist is: 58.65.
<h3>Length</h3>Let the length of hypotenuse be x
Using Pythagorean theorems
x²=(19-15)²+12²
x²=16+144
x²=160
x=√160
x=12.649
x=12.65 (Approximately)
Hence:
Total length:
Total length=12.65+15+12+19
Total length=58.65
Therefore according to the floor plan, the one that is closest to the total length, in feet, of the walls that Kamal should quote to the artist is: 58.65.

For this case we have:
If after 2 hours the marathon runner has traveled 22 kilometers we have:
2h -----------> 22km
Applying a rule of three, we can know the time it takes to run 42km. So, we have:
2h -----------> 22km
x -------------> 42km
Where "x" is the time it takes to travel 42km. Resolving we have:
Thus, after 3.82 hours the marathon runner will travel 42km.
Answer:
