There are linear feet, and square feet, but no "linear square feet".
Multiply by 144.
In order to calculate the square footage you need to find the length and the width of the room in feet. You multiply the length and the width to give you the square footage of the room
I think (hope) you mean square, not linear. Answer is 18 ft2
Multiply 20 X 11 to get 220 square feet. 220 square feet = 22.4 square yards. There are 9 square feet in a square yard. So divide 220 by 9.
You can't calculate linear footage based on square yardage alone. If you meant square footage it will cover 810 sq. ft..
There's no way to calculate that just from square footage.

In order to calculate the square footage you need to find the length and the width of the room in feet. You multiply the length and the width to give you the square footage of the room
To calculate square footage of a pipe you need to use the area formula of a circle, a=1/2bh. then find the circumference of the entire pipe.

To calculate the linear square footage of a boat, you would measure the length of the boat in feet and multiply it by the average beam (width) of the boat in feet. This will give you the total square footage of the boat's surface area. Keep in mind that this calculation assumes the boat's hull has a rectangular shape, so it may not be entirely accurate for boats with irregular shapes.
Multiply 20 X 11 to get 220 square feet. 220 square feet = 22.4 square yards. There are 9 square feet in a square yard. So divide 220 by 9.
If you know the length ft.(linear) and you wish to know its area (sq. footage), you must also know the width. Length (ft.) x Width (ft.) equals area or sq. feet. Linear in this case refers to length.
Measure the length of each wall. Add those figures up and you get Linear footage. Divide the total linear footage by the width of the panels and round up, this is the number of planks you will need.
