It could be a wall that is 1 square foot in cross section and 47 feet long.
Feet are the same as linear feet. Linear just distinguishes them clearly from square feet or cubic feet.
The distance around the wall is 42 linear feet.
To calculate linear yards for wallpaper, first measure the height and width of each wall you plan to cover. Multiply the height by the width to find the total square footage for each wall, then sum the areas of all walls. Since wallpaper is usually sold in rolls measured in square feet, convert the total square footage to linear yards by dividing the total square footage by 9 (since one linear yard equals 3 feet). Finally, consider the pattern repeat and any waste to determine the total amount of wallpaper needed.
To frame a space of 240 square feet, you'll need to calculate the perimeter and the amount of framing required. Assuming standard wall height and no windows or doors, you can estimate that you will need approximately 1 linear foot of 2x4 for every square foot of wall area. This means you would need about 240 linear feet of 2x4. Since a standard 2x4 is 8 feet long, you would require around 30 pieces of 2x4 (240 ÷ 8 = 30).
96 square feet.
How big is a wall that is 15 square feet?
Sorry, wrong question - a linear foot is a measure of length - a square foot is a measure of area. How many inches fit into a gallon? How many quarts is it from here to the moon? Get the idea?
Area of wall: 17 times 17 = 289 square feet
Two squares of vinyl siding cover 200 square feet, as one square equals 100 square feet. Therefore, two squares would be 200 square feet total. If you need the linear footage, you'll need to consider the height of the installation, as that will affect how many feet of siding is required. For example, if you're installing the siding on a wall that is 8 feet high, you'd need 25 feet of siding (200 square feet ÷ 8 feet).
9 square feet = 1 square yard Area of the wall (each side of it) = 9' x 13' = 117 square feet = 13 square yards.
Unless you are speaking of something else, that is just a retaining wall in Sierra, Nevada.
If you have to ask.... You can't afford it.
