60 feet. Sorry, thought that was obvious.
90 square feet
It's the parameter, so it's 2L+2W, which is 38 feet.
Perimeter is in feet and not in square 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.
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
90 square feet
It's the parameter, so it's 2L+2W, which is 38 feet.
you will need 84 sq. yards of wallpaper

A 2-foot border around a 20 x 14 area makes the area 24 x 18 making the perimeter 84 feet.
The perimeter is 288 feet.
A perimeter IS a linear measure so a perimeter of 84 feet is a length of 84 feet.
