Answer:
<h2>84, 42</h2>
Step-by-step explanation:

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 = <u>1</u><u>8</u><u>9</u><u>0</u><u> </u><u>hectares</u><u>.</u>
And we are done !!
