Question

a container of plant food recommends an appilcation rate of 630g/ha. If the container holds 15kg of plant food, how many square meters will it cover? (1 ha=10000 m^2)

Answer 1

Answer:
50 kg \ 10,000 m2 = 0.005 kg\m2
so 10 kg \ 0.005 = 2000
so for each 10 kg covers 2000 m2
keeping in mind each square meter gets 0.005 kg of the strong food
so how many 0.005 kg are in 10 kg`s ? , the answer is 2000 and thats the number of square meters.
