AI Drawing Prompt Reference

Given a fixed perimeter, draw the largest possible rectangle. First, draw a line segment with a length equal to half the perimeter. Then, take a point on this segment as one vertex of the rectangle. Next, draw two lines perpendicular to this segment, intersecting the y-axis and x-axis to form the other two vertices of the rectangle. Finally, connect these points to form the rectangle.
