Difference between Area and Perimeter

 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.

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 the basic differences along with some of the basic features and calculating the Area & Perimeter for those shapes.

Area: 

• The area is the region occupied by a closed shape in a two-dimensional plane.
• It is measured in square units
• Example: Area of a plot for farming
• Area of square = side²
• Area of a rectangle = Length × Breadth
• Area of triangle = ½ × base × height
• Area of rhombus = ½ (product of diagonals)
• Area of trapezium = ½ (sum of parallel sides)

Perimeter: 

• Perimeter is the length of the outer boundary  of a closed shape
• It is measured in units
• Example: Fencing the agricultural plot
• Perimeter of square = 4 x side
• Perimeter of rectangle = 2(Length+Breadth)
• Perimeter of triangle = Sum of all three sides
• Perimeter of rhombus = 4 × side
• Perimeter of trapezium = sum of all sides
