The question is not clear; the answer depends on whether you interpret "the blue part" to mean: 1) the part of the blue square that is still visible after the red square is placed on top of it, or 2) the entire blue square, including the part that is under the red square. In case 1, the answer is "they are equal." In case 2, the answer is "the red part has half the area of the blue part."
