I'm pretty sure 25 pounds of fertilizer should do it.

f is greater than or equal to 40 pounds
5 and a bit ;)

If depends on what kind of rock it is. Each rock has a different weight due to size and density.
at least 40 pounds of fertilizer is needed to adequately cover your backyard. let f= the amount of fertilizer needed

(7,125/3,325) x 7 = 15 sacks
20ft. x 20ft.
144

9 square feet.

The geometric term for the number of square units needed to cover a surface is called the area of said surface.
