A plot of land will be composed of a rectangular region of grass with one semicircle at the end as shown. The grassy region inside the plot of land must have an area of 700 square feet. (a) Find the total outer perimeter of the plot of land, P, only in terms of r, the radius of the semicircie. P(A) = x + 700 2r + r PC) x+r+ 700 PC) = 2700 r PA) XP + 350 P()
