Samantha is wall papering her bedroom and wants to make sure that she bought enough wall paper. Each wall in her room measures 10 feet by 11 feet. How many rolls of wall paper will Samantha need if each roll covers a total of 25 square feet.

4.4 rolls of wallpaper

Step-by-step explanation:

Dimensions of Samantha's room= 10 feet by 11 feet

Length= 11 feet

Width= 10 feet

Area of Samantha's room= Length × width

= 11 feet × 10 feet

= 110 square feet

Each roll covers a total of 25 square feet

Total rolls of wallpaper = Area of the room / Area covered by each roll

=110 square feet / 25 square feet

= 4 10/25

= 4 2/5

= 4.4 rolls
