### How to calculate area?

Here are the important and useful area formulas for sixteen geometric shapes:**Square area** A = a2**Rectangle** A = a x b**Triangle**

A = b x h / 2

A = 0.5 x a x b x sin (γ)

A = 0.25 x √ ((a + b + c) x ( -a + b + c) x ( a – b + c) x ( a + b – C) )

A = a2 x sin (β) x sin (γ) / (2 x sin (β + γ))**Circle area** A = πr2**Circle sector** A = r2 x angle / 2**Ellipse** A = a x b x π**Parallelogram **

A = a x h

A = a x b x sin (angle)

A = e x f x sin (angle)**Rhombus **

A = a x h

A = (e x f) / 2

A = s2 x sin (angle)**Pentagon** A = a2 x √ (25 + 10√5) / 4**Hexagon** A = 3/2 x √3 x a2**Octagon** A = 2 x (1 + √2) x a2**Quadrilateral** A = e x f x sin (angle)

### How do I calculate the area of an irregular shape?

Calculate the Area of an irregular shape:

- Divide the shape into several sub-shapes for which you can do the area calculations like triangles, rectangles, trapezoids, circles, etc.
- Calculate the area of each of these sub-shapes.
- Sum up the areas of sub-shapes to get the final result.

### How to calculate the area of the square?

The simplicity of the square is one of the first shapes that geometry students became familiar with. Based on real-life measurements, it is used in construction, landscaping, engineering, etc. A square can be interpreted as a special case of a rhombus, a rectangle in which the opposite sides are equal in length, and its entire length is 90o. **Calculate All the Shapes of the Area** of more advanced shapes. The equation's solution is straightforward multiplication, which is the formula used in the area of a square online calculator. Using this calculator, you can easily calculate the area of a square of a given length of its side in any metric: mm, cm, meters, km, inches, feet, yards, etc.

### What are the properties of a rectangle?

Rectangles have some interesting properties:

- Cyclic –all corners lie on a single circle
- Equiangular – corner angles are equal to 90 degrees
- Rectilinear – sides meet at right angles
- Two lines of reflection symmetry – vertical and horizontal through the center
- Two diagonals bisect each other - length using the Pythagorean theorem

### How to use the area of the circle calculator?

The **Area of a Circle**, its diameter, and its radius can easily calculate everything. The steps are as follows:

- Determine whether your given value is a diameter or a radius based on the definition
- Enter your value into the proper field of the calculator
- Finally, your results are here.
