Top left - We have a half circle with a radius of ( 8 - 4 + 2)  / 2 = 6/2 = 3     area =     3.14 * 2^2 =  12.56   km^2

 

Center - We have  an 8  x 2 rectangle  =  16   km^2

 

And, at the bottom  we have a   5 x 8  rectangle = 40  km^2

 

Total area = 

 

12.56 + 16 + 40 = 

 

68 .56    km^2

8(5) + 8(2) + 1/2 * 3.14(8+2-4)^2/2

40 + 16 + 1/2 * 3.14 (3^2)

40 + 16 + 14.13

70.13 km^2
