Geometry is used in everyday life for building and construction, home decorating, outdoor projects and professional work. The geometric formulas for area and perimeter are often used to accomplish projects that require room and object measurements. For squares and rectangles, the area = base x height and the perimeter = base x 2 + height x 2.
The measurements for the area and perimeter of a floor are necessary for carpet and tile installation both in rectangular and irregularly-shaped rooms. They also assist interior designers with creating floor plans and choosing the correct size of furniture, tables and rugs. Outdoor projects make use of geometry as well. A gardener may calculate the number of cubic feet of soil needed to sustain plants or to fill a raised bed. In this case, the correct equation would be base x height x width. The formula for finding a perimeter may be used to determine how much wood to purchase for building a fence around a yard. Area and perimeter formulas are also helpful for constructing craft projects, informational posters, and frames for artwork. Many professionals, such as architects, engineers, carpenters and construction workers, rely on advanced geometric principles to perform their work.
