Question 1144667
An acre field has 3 plants per hill.  The rows are 3'6" apart, with hills 3'6" apart. **

Calculate total number of plants.

3'6" = 3.5 ft.

An acre = 43560 ft.

p = number of plants.
-------------
Each plant has an area of 3.5*3.5 sq ft = 12.25 sq ft
-----
43560/12.25 =~ 3555 plants
==========================
But, p might vary with the shape.
If the field is a triangle or a circle or some other shape the # can be different.
