The fief was an important basis for feudalism because it was the land given by a landlord to a vassal in return for military service
Not only their military service, the vassals were also obligated to give some cut for the landlord for every profit made using the land

When we have a 75% of the wound healed, we have the following area:
area of the wound=(100%-75%) (initial area) =25% (initial area)
In this case:
area of the wound=25%(80 cm²)=20 cm²
A(t)=80(10^-0.023t)
If A(t)=20
Then:
20=80(10^-0.023t)
10^-0.023t=20/80
10^-0.023t=0.25
log (10^-0.023t)=log 0.25
-0.023t log 10=log0.25 log 10=1
-0.023t=log0.25
t=log 0.25 /-0.023
t=26.176≈26
The wound be healed (75%) in 26 days
France and England developed a sense of nationalism and the power of the French monarch increased, while England became ensued in civil war
