60 feet. Sorry, thought that was obvious.
90 square feet
It's the parameter, so it's 2L+2W, which is 38 feet.
The perimeter is the sum of all the sides of the figure. The perimeter cannot be determined just by area alone, other dimension(s) are needed unless you are referring to a circle in which case the perimeter would be the circumference which in that case would be 6.77 feet.
Perimeter is in feet and not in square feet
A 2-foot border around a 20 x 14 area makes the area 24 x 18 making the perimeter 84 feet.
Perimeter = 38 feet Area = 90 square feet
11 + 9 + 11 + 9 = 40 feet

A perimeter is the border round an area. As to the area, imagine a field 200 feet by 50 feet: 200 × 50 = 10,000 square feet. The distance round the edge would be 500 ft. You might need this if you wanted to know the necessary length of a fence.
Wallpaper usually is hung in a vertical manner: from the top of the wall to the bottom. If the wallpaper is 10 feet long, it means that it will cover a space that measures 10 feet or 120 inches. The specific measurement mentioned in the question means that piece of wallpaper will cover an area 10 feet tall and 9 feet wide.
