The path is the hypotenuse of a right triangle with legs 30 and 120.
30² + 120² = c²
900 + 14400 = c²
15300 = c²
c=√15300 ≈123.7'
instead of walking 30+120=150 feet they save 26.3 feet by taking the shortcut

Answer:
part a:60 part b:9
Step-by-step explanation:
part a:
5,10,15,20,25,30,35,40,45,50,55,60,65
12,24,36,48,60
60 is the lowest number that's common in both
part b:
72=2×2×2×3×3×8
81=3×3×3×3
