Answer:
258.41 m
Step-by-step explanation:
Since there are three semi-circles in the length of the rectangle, we can divide 18 by 3 to get 6 as the diameter for each circle. The area of a semi-circle is (pi*r^2)/2, we can multiply that by 3 and add it with the area of the rectangle to get the total area.
(12*18) + (3(pi*3^2))/2 =
216 + 42.4115 =
258.41 m
