Astudy of how much corn was produced in a field depending on the planting density compared the yield from fields planted with 4 plants per hectare to the yield from fields planted with 6 plants per hectare.
1. what is the ratio of the distance between the corn plants in the more-densely-planted field to the distance between the corn plants in the less-densely-planted field?

Or in the other way:

Explanation:

For this case we need to remember that hectare is a measure of area. And we have the following ratios:

We can convert this into

We can convert this into

By dimensional analysis we assume that we can find the ratio in terms of distance like this:

And if we find the ratios in terms of distance we got:
