Assume you have a rectangular area such as a room and, for example, you want to calculate the square footage area for flooring or carpet. The way to calculate a rectangular area is by measuring the length and width of your area then multiplying those two numbers together to get the area in feet squared (ft2).

square measurement is length X width
so it is 3 meters wide and you want 300 square meters that will be 100 meters X the 3 meters wide = 300 sq meters and that will around a full roll

Instructions

1. Measure the rectangle length, width and height. For example, 8 inches long, 6 inches wide, 10 inches high.
   
2. Multiply the length by the height, then double the product. With this example, 8 inches multiplied by 10 inches results in 80 square inches, which multiplied by 2 equals 160 square inches.
   
3. Multiply the width by the length, then double the product. With this example, 6 inches multiplied by 8 inches equals 48 square inches, which multiplied by 2 equals 96 square inches.
   
4. Multiply the height by the width, then double the product. With this example, 10 inches multiplied by 6 inches results in 60 square inches, which multiplied by 2 equals 120 square inches.
   
5. Sum the amounts from Steps 1 through 3 to find the rectangle surface area. So adding 160, 96 and 120 square inches results in 376 square inches.

It equals zero square feet.
Linear feet is only one dimension (length). You need 2 dimensions to calculate square feet. In other words, you need *width* also.
But IF you're asking how many square feet is 9 linear feet (long) by 9 linear feet (wide), then the answer is 81.
