a farmer has the option to purchase two different types of irrigation systems for a square plot of land. One system has a large circular coverage area while the other has four smaller circular coverage areas.

use the space below to show cwhich irrigation will be better for the farmer even though the size of the plot is unknown.

a = pi(x/2)^2 = pix^2/4
a = 4pi(x/4)^2 = 4pix^2/16 = pix^2/4

any help would be nice.. i'm highly confused by this question.. v.v
