Area versus perimeter

The perimeter is the length of the outline of a shape.

The key difference between area and perimeter is: area is the region occupied by shape and perimeter defines the length of the outer boundary of the shape. Both the parameters define the size of a shape. Learn more on perimeter and area here. One can easily get confused between these terms which looks similar but have a huge difference between them. It is measured in square units.

Area versus perimeter

Perimeter for a 2-dimensional shape is the total distance around the respective shape. For the figures with straight sides such as triangle, rectangle, square or a polygon; the perimeter is the sum of lengths for all the sides. The area for a 2-dimensional shape is the space enclosed within the perimeter of the given shape. To calculate the area for different shapes, use different formulas based on the number of sides and other characteristics such as angles between the sides. If all the measurements are in centimeter, the units of measurement for the perimeter and area of different shapes are:. Thus, the unit of measurement remains the same, as cm. The unit of measurement is unit2 or cm2. The concepts of area and perimeter are the basis for understanding Euclidean geometry and calculating the volume of solid shapes in 3-dimensional space such as cones, prism, sphere, and cylinder. Also, we use these formulas for calculating the area and perimeter for quadrilaterals and polygons comprising of sides and curves. The real-life utility of the concept is in several fields such as mapping, architecture, and surveying. The geometric representation of figures is done by sketching the distances and areas for clear understanding. Three-dimensional objects derived from 2-dimensional shapes and land surveying in fields.

What is the difference between the perimeter and area of a shape? Above is the graph of a square yard. The brown border is a fence, while green square is the grass. Think of a two dimensional closed geometric shape, such as a triangle or a square. The continuous line that forms the border closing the shape is called the perimeter.

We use the terms area and perimeter quite often in the classroom. We also know that area and perimeter are characteristi cs related to geometrical shapes. As we go further, we will learn the difference between area and perimeter and the steps involved in calculating area and perimeter. Read More Read Less. Area and perimeter are two important properties of two-dimensional shapes. We use the concept of area and perimeter to describe the size of shapes. In general, small shapes will have a smaller area and perimeter. On the other hand, bigger shapes will cover a larger area and will have a longer perimeter. But in some cases, the shape can have a long boundary, and a smaller area at the same time.
