First let’s find the area of the two semi circles. The formula is n*r^2/2
n*half of 15 to find our radius= 7.5^2/2=area of semi circle 1.
Area of first semi circle is 88.357
Area of second semi circle is 88.357
Now we find the middle which is a rectangle
Area of rectangle= L*W
Area= 60
Add them up to get 88.357*2+60
236.714
