Well, if you think about it, its a half circle. We know that if the dog pulls straight then the radius if this were a full circle would be 7. So the Area of a circle is A=Pi Radius Square. For us it will be divided by 2 since its a half circle. So were going to round pi to 3.14 and now..
3.14(49)=153.86. So that is an area of the full circle. DIvided by 2 we get 76.93.
I am pretty sure its correct so your answer is 76.93 m
