Because Anastasia is bored at home during the quarantine, she decides to redecorate. The dimensions of her living room are approximately 18 ft x 12 ft with a nine-foot ceiling. Instead of painting the walls like an average person would, she wants to cover them with burgundy wallpaper.

Part A: If one roll of wallpaper covers 50
2
, then determine how many rolls of wallpaper is needed to cover the living room.

Part B: If one roll of paper cost $15.90, then determine the cost of the wallpaper (before taxes).

6 rolls of paper is needed to cover the living room

The cost of the 6 rolls is $95.40

Step-by-step explanation:

There are four walls here, two 12 ft by 9ft walls, and two 18 ft by 9ft walls

Area of a rectangle = length * height

Area of walls 1&3 = 18 * 9 = 162

Area of walls 2&4 = 12 * 9 = 108

Total area of walls = 162 + 108 = 270

One roll for every 50

270 ÷ 50 = 5.4 rolls

Since you cant buy 0.4 rolls of wallpaper, you need to buy one whole roll instead

6 rolls of paper is needed to cover the living room

One roll costs $15.90

6 rolls * 15.90 = $95.40
