The formula to calculate the square footage of an area that is square or rectangular in shape is length multiplied by width equals the area's square footage. For example, if a rectangular shaped room measures 11 feet in length and 13 feet in width, 11 multiplied by 13 equals 143 square feet.
Know MoreThe formula to calculate square footage varies based on an area's shape. For a triangle, the width of the base is multiplied by the height of a triangle. This figure is then multiplied by a half. If the base measures 4, and the height is 5, 4 is multiplied by 5 and then multiplied by a half, equaling 10 square feet.
A parallelogram's square footage is determined by multiplying the base (a measure of width) times the height. A base of 10 and a height of 6 are multiplied together to yield 60 square feet.
Learn MoreThe square footage of a house is found by multiplying length times width, so a house that is 30 feet by 40 feet measures 1,200 square feet, assuming the house has only one story. The square footage of additional stories should be added as part of the total square footage.
Full Answer >To figure out the square footage of an area, you will need a measuring tape and possibly a calculator. Measure length and width and then multiply the two together. The process should take less than five minutes.
Full Answer >To determine the square footage of a rectangle, multiply the length by the width. The answer is in given square units. For example, if a lawn is 20 feet by 30 feet, the measurement is 600 square feet. This is also referred to as "area."
Full Answer >To convert feet to square feet for a rectangular area, find the length of the area you are measuring, and multiply it by the width of the area. A square foot is a measurement unit equal to a square that measures one foot on each side.
