A rectangular building is 4 meters by 6 meters. A dog is tied to a rope that is 10 meters long, and the other end is tied to the midpoint of one of the long sides of the building. Find the total area of the region that the dog can reach (not including the inside of the building), in square meters.

The area of the region is 72*pi.

Have you tried drawing this.  You will not get it without a picture.

 

You will end up with a half a big circle and a quarter of 2 little circles.     the area of a circl is pi*r^2

 

Try if for yourself

 

Note that the other answer already given is incorrect.
