Realise that Q + R gives you a triangle.
This triangle has the same height as the rectangle and its base is the length of the rectangle.
So, this tells you that the triangle's area is ½ of the rectangle. And therefore S+T must be also ½ the area of the rectangle since S and T occupies the rest of the rectangle
