In Argentina, a cow on a ranch is expected to need an average of 4200 m2 of grassland for food.
What size does a ranch need to be to feed 4500 cows?
Give your answer in hectares.

The cows of Argentina needs an approximate area of 4200 m² for grazing, and there is a total of 4500 cows.

And we are asked to find the total area of their grazing but in hectares. So, we can write:

Then, for 4500 cows:

We know that, 1 hectares = 10000 m² = 10⁴ m²

Then let the area of the field be x in hectares:

Then, putting them in proportion, We will get:

So, the total area in hectares = 1890 hectares.

And we are done !!
