Answer:
714m^2
Explanation:
So, as we said in the comments, since they didn't give the radius, we have to assume the center is a square. That means the area of the center part is 20m x 20m, and the diameter of the circular ends is 20m as well.
Area of center: 20 x 20 = 400m^2
Area of ends:
Area = (pi)(r)^2
The radius = 1/2 the diameter = 10m
Area = (3.14)(10)(10)
Area = 3.14 x 100 = 314m^2
Now, if it only had one semicircle on the end like your previous question, we'd have to divide this answer by 2, but the circular area we just calculated covers both ends, so the total area = the square center + the circular area
400 + 314 = 714m^2
