You are given a country lot with an area of 18.0 acres. You are asked to find the area in hectares. From the established conversion, 1 hectare is equivalent to 2.47 acres. All you need to do is to divide the given area by the acres to get the equivalent hectare.
land area = 18.0 acre (1 hectare / 2.47 acre)
land area = 7.287 hectare
and since the given number of significant figures is three, then round off the 8 to 9 since the succeeding number of 8 is 7. and the final answer is
land area = 7.29 hectares.
