Answer 1

If the shaded region is the triangle with the left side as base, area = 49 (one-half of the square)

If the shaded region is the two triangles with bases on the right side as base, area = 49 (one-have of square)

Considering this is a standardized test question, the solution probably is a non-pencil.
