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."
Know MoreThe measurement is always described in square units. It does not matter if the object is measured in miles, yards, feet, inches, kilometers, meters, centimeters or millimeters. Some professionals need to be able to calculate square footage in their daily work. For instance, painters must first know the area of the room they are going to paint in order to purchase the correct amount of paint.

Full Answer >To calculate square footage of rectangular floor space, determine the length and width of the rectangular space in feet, then multiply them together. If floor space is not a perfect rectangle, break the space up into rectangles, calculate the area of each rectangle, and find the sum of the combined areas.
Full Answer >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.
Full Answer >A rectangular prism's formula is given as length (l) multiplied by the width (w) and height (h), or with the formula V = l * w * h. A rectangular prism is a three-dimensional figure that has six rectangular faces, and all the angles are right angles.
