To determine the area of the rectangle PQRS, I need the following details:

1. The lengths of the sides or the dimensions of the rectangle (i.e., the lengths of the sides PQ and PS or any other two sides).
2. If you have any specific coordinates for the vertices, I can calculate the area based on the coordinates as well.

Could you provide these details?

Once I have the necessary information, I can easily calculate the area of the rectangle. If you have a diagram or image, feel free to upload it!
