Question

Alyssa wants to cover 2 of her bedroom walls with floral wallpaper. The total area of the two walls is 23 square meters. One roll of wallpaper covers 8 square meters. If Home Depot only sells full rolls of wallpaper, what is the least number of rolls Alyssa will need to cover the walls?A. 1 rollB. 2 rollsC. 3 rollsD. 4 rolls

Answer 1

In order to find the number of rolls, we need to divide the total area over the amount each roll will cover.

`(23)/(8)=2.875`

However, since home depot only sells full rolls we need to round to the closest full roll which in this case is 3.

Alyssa will need 3 rolls to cover the walls
