Leokris [45]

Answer:3621.41

Step-by-step explanation:

Given

Phone line runs along east for 1.4 miles

then 2.5 miles along north

It costs 3500 currency per mile

Total distance=1.4+2.5=3.9

Cost=3.9\times 3500=13,650

For diagonal running

Length=\sqrt{1.4^2+2.5^2}=2.865

Cost=2.865\times 3500=10,028.58

Thus currency saved =13,650-10,028.58=3621.41
