Find the area of the field

if the rectangular part is 95 yds long and the diameter of the semicircles is 49 yds, the area is:
95*49

that's just for rectangular area

now add those two semicircles and find the whole area of a circle
A = pi*r^2 = pi * (49/2)^2

Total area:
95*49+pi*(49/2)^2
Total cost:
$0.08*(95*49+pi*(49/2)^2)
