The area to the LEFT of the center of the circle is given by

1km x . 8km  = .8km^2

Subtract the 1/2 circle area :   - 1/2 pi (.8km/2)^2 = - .2513 km^2

 

.8 - .2513 = .5486 km^2

 

Total rectangular area is      (1+1.4)km x (.8 km) = 1.92 km^2

 

.5486 km^2/ 1.92 km^2 = .286   = 28.6 % chance of landing in that little area...
