Cake division problem for 6th graders

The cake is in the shape of a large rectangle with a small part missing as shown. Can you find a way to divide the cake evenly with just one cut?

Tam and Hang prepared a birthday cake for Tung. The cake was rectangular. It was delicious! While Tam was decorating it, Hang couldn’t resist the delicious taste of the cake so she secretly cut and ate a rectangular part as shown in the picture.

At the party, Tung and Tam wanted to punish Hang for eating first. They decided not to share the cake with Hang anymore. They wanted to divide the remaining cake equally to eat.

With a straight cut and 3 minutes of thinking, help Tung and Tam divide the cake.
