If you would like to know which rug will cover the greater area, you can calculate this using the following steps:
a square: 6.3 feet * 6.3 feet = 39.69 square feet
a rectangle: 4.8 feet * 8.2 feet = 39.36 square feet
39.69 > 39.36
The correct answer would be: A square rug will cover the greater area.
