The student's answer is wrong. When a point (a, b) is reflected across the line y=x, the coordinates of the new point is reversed to (b, a). So D(2, 5) would become (5, 2), E(6, 4) would become (4, 6), and F(3, 3) is still (3, 3). None of the new points is (2, -5).
Answer: 200 in squared

Each of the triangles in this picture are the same. You can tell because it's a square, and because of the dotted line.
Take the white triangle and substitute it for one of the black ones. Now, you have this.
Now, just do 10 * 20
= 200
Answer:
