The population density of Tridex in an abandoned square farm land of side 200 m was found to be 5 plants per m2. The population size of the plant on the farm is

Answer Details

To calculate the population size of Tridex on the farm, we need to know the total area of the farm land. Since the farm land is square and has a side length of 200 m, the area is given by the formula: Area = Side length x Side length Area = 200 m x 200 m Area = 40,000 m2 Now, we know that the population density of Tridex is 5 plants per m2. To find the population size, we need to multiply the population density by the total area of the farm: Population size = Population density x Area Population size = 5 plants/m2 x 40,000 m2 Population size = 200,000 plants Therefore, the population size of Tridex on the farm is 200,000. Option (d) is the correct answer.
