A foot is a unit of distance. A square foot is a unit of area. The two units are therefore incompatible.
To calculate the square feet of a roll of paper towels, first determine the dimensions of the roll. Measure the width of the paper towel (in feet) and the length of the roll (also in feet). Multiply these two measurements together: Square Feet = Width (ft) × Length (ft). If the length is given in yards or inches, convert it to feet before performing the calculation.
You must convert each measurement (length and width) from whatever unit of measurement you have used into feet; then multiply the length (in feet) times the width (in feet). The result will be the area in square feet.
To find the square footage of a rectangular room, you multiply the length by the width. In this case, the length is 12 feet and the width is 27 feet. So, the square footage of the room would be 12 feet x 27 feet = 324 square feet.
To find the square feet of carpet for a room, measure the length and width of the room in feet. Then, multiply the length by the width to get the square footage. For example, a room that is 10 feet by 12 feet would require 120 square feet of carpet.
360 square feet. Multiply the length by the width. The result is the area in square feet.
In feet: Width x Length = Square Feet In inches: (width x length) /144= Square Feet
to calculate square feet its width X length 10x35 =350 or 20x17.5 =350
You don't measure the length and width in square feet. Square feet is an area. You measure the length and width in feet, then multiply them to get the area in square feet.
