Answer:
There is 160.81 % of increase.
Step-by-step explanation:
Given that,
The average size of a privately owned farm in a particular country was 171 acres.
Now, the average size of a privately owned farm in the country had increased to 446 acres.
We need to find the percent increase.
[tex]\%=\dfrac{\text{increase}}{\text{original}}\times 100\\\\\%=\dfrac{446-171}{171}\times 100\\\\\%=160.81\%[/tex]
So, there is 160.81 % of increase.
