Answer

First, draw a rough diagram
Step 1: The base CD measuring length 4 cm can be easily constructed.
Step 2: Draw a perpendicular to line DC at the point C. Let us call this line l.
Step 3: Draw an arc of radius 8 cm with point D as the center.
To locate the point B,
Step 4: Draw perpendiculars to DC and BC passing through D and B, respectively. The point where these lines intersect is the fourth point A.
It satisfies all conditions of the rectangle.
