Given that Area of the rectangular room = 182 square feet

Width of room = 13 feet

we can plug these values into formula of area of the rectangle to find the length

Area = Length * Width

182 = Length * 13

[tex] \frac{182}{13} = Length [/tex]

14 = Length


We have to find about how much wallpaper border will be needed to go around the top of all four walls of her bedroom.

In other words we need to find the perimeter of the Room

Perimeter of the rectangular room = 2 (Lenght + Width)

Perimeter of the rectangular room = 2 (14+13) = 2(27) = 54 feet


Now lets check how much wallpaper is available.

there are 4 rolls of border wallpaper. Each contains 12 feet

So total wallpaper available = 4*12 = 48 feet


But we need 54 feet which is more than available border wallpaper.

That means Megan doesn't have enough wallpaper border to go around the top of all four walls of her bedroom
