Difference between Area and Perimeter

In mathematics, Area & Perimeter both seem to be important terms in Geometry. One can easily get confused between these terms which looks similar but have a huge difference between them. Here we will discuss about the basic differences along with some of the basic features and calculating the Area & Perimeter for those shapes.

Area- Area is defined as the space/region occupied by a two-dimensional flat object. It is measured in square units.

Consider a square having side ‘a’ then the area is defined as \(a^{2}\).

Perimeter- Perimeter is defined as the length of boundaries of a closed figure. Consider for an example a square having side length to be ‘a,’ then the perimeter is defined as sum of all the four sides, i.e. ‘4a.’

The measurement of Perimeter is in unit.
