DeMarco draws △PQR with vertices P(−4, 2) , Q(2, 2) , and R(2, −6) . Then he dilates the triangle with a scale factor of 5 to create △P′Q′R′. How are the areas of the triangles related?

The area of the larger triangle will be   (scale factor)^2  =  25 times as much as the area of the smaller triangle
