Answer:
Perhaps, she is interested in finding the area enclosed by this triangular park.
Step-by-step explanation:
The area of the triangle enclosed by the three points
A(1,1), B(1,4) and C(-3,4) in this question will be given by
 |Ax ( By  − Cy)+ Bx(Cy−Ay)+ Cx(Ay− By) |/2  
=|1(4-4)+1(4-1)+-3(1-4)|/2=10/5= 5 sq. units.
