Answer:
154%
Explanation:
First, we need to calculate the increase in size of the privately owned farm:
increase = new value - old value
increase = 432 - 170
increase = 262
Next, we can use the formula to calculate the percent increase:
percent increase = (262 / 170) x 100%
percent increase = 1.54 x 100%
percent increase = 154%
Therefore, the percent increase in the size of privately owned farms in the country is 154%.
