Answer:

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 [tex]ft^{2}[/tex]

Area of walls 2&4 = 12 * 9 = 108 [tex]ft^{2}[/tex]

Total area of walls = 162 + 108 = 270 [tex]ft^{2}[/tex]

One roll for every 50 [tex]ft^{2}[/tex]

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
