Ответ:
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
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
