Area Calculator:

An area calculator figures out how much space is inside a shape or an area. You can use it to measure the size of a room, a piece of land, or any other space you want to know about. To use an area calculator, you typically need to input some measurements, like the length and width of the shape whose area is required, and the calculator will then do the math for you to give you the total area in square units, such as square feet or meters. It's a handy tool for various tasks, from home improvement projects to determining the size of a garden or a piece of real estate.

Area of Rectangle:

A rectangle is a four-sided polygon with four right angles, which means that all its angles are 90 degrees. The opposite sides of a rectangle are parallel and of equal length. In other words, a rectangle is a quadrilateral with four sides so that opposite two are both similar and equivalent in length.

Area = Length × Width


  • Enter the value of the length
  • Enter the value of the width

Area of circle:

A circle is a 2-D geometric shape that consists of all the points in a plane that are equidistant from a single fixed point called the centre. The distance between the centre and any point on the circumference of the circle is called the radius.

Area = πr2

Where "Area" is the total surface enclosed by the circle, "π" (pi) is a constant equal to 3.141 and "r" is the radius of the circle.


  • Enter the value of the radius

Area of a sector:

A sector is a portion of a circular region, like a slice of a pie, that is formed by two radii (plural of radius) and the arc between them. 

Area of Sector = (θ/360) πr2


  • Enter the value of the radius of the circle
  • Enter angle

Area of Parallelogram:

A parallelogram is a quadrilateral characterized by having parallel opposite sides. Within a parallelogram, opposing sides have equal lengths, and opposing angles possess congruent measures.

The most common way to represent a parallelogram is with a pair of parallel lines and pairs of equal-length sides.

Area= (hight)(base)


  • Enter the value of Hight
  • Enter the value of the base

Application of online area calculator:

  • Room Size: You can use it to find out how big a room is. Just measure the length and width of the room, and the area calculator will tell you how many square feet or square meters it is.
  • Gardens and Yards: For a garden or yard, you can measure the length and width of the area you want to plant or cover with grass. The area calculator will give you the total square footage to know how many plants or how much grass you'll need.
  • Painting: When you want to paint a wall or a fence, you can measure the area to determine how much paint you'll need. This helps you buy the right amount of paint.
  • Carpet or Flooring: If you're getting new carpet or flooring, measuring the area can help you buy the correct amount and save money.
  • Land or Property: For bigger areas, like land or property, you can use the calculator to find out the total square footage or acres. It's handy for real estate or construction.
  • Arts and Crafts: In arts and crafts projects, you need to know the area of a surface you're working on, like a canvas or paper. The calculator helps you plan your art projects.
  • Agriculture: Farmers use area calculators to measure fields and know how much seed, fertilizer, or irrigation is needed.
  • DIY Projects: When doing DIY projects, such as building a deck or a shed, you can measure the area to buy the right amount of materials like wood or roofing.
  • Geometry and Education: Students and teachers use area calculators to learn and teach about shapes, like triangles, rectangles, and circles.
  • Construction: Architects and builders use area calculators to plan construction projects and estimate material requirements.
