# Area of a Triangle Calculator

**Area of Triangle -**The area of a triangle is defined as the total space that is enclosed by any particular triangle. The basic formula to find the area of a given triangle is A = 1/2 × b × h, where b is the base and h is the height of the given triangle.

### What is meant by Area of Triangle?

The area is defined as the region occupied by the Triangle. Usually, Triangle is a two-dimensional figure that has three edges and three vertices. Depending on the sides and angles triangle can be classified into many types. The most important property of the triangle is that the sum of the interior angles of a triangle is 180 degrees. As triangle is a 2D figure it has both area and perimeter.

### How to find the Area of Triangle?

Triangle is the most basic shape and almost everyone remembers it right from the school.

** Area of triangle = (1/2)bh Square Units**

Where b is the base of the triangle and h is the height of the triangle.

However, in certain cases, it is difficult to find the height of the triangle. In such cases, you can use different equations depending on the data you know about the triangle.

**Three Sides(SSS)**

If you know the three sides of a triangle then you can go with Heron's formula i.e.

** Area = √(s * (s - a) * (s - b) * (s - c))**

where "s" is the semi perimeter and is half of the perimeter of the triangle i.e. s = (a + b + c) / 2

the other way of getting the area is to use the lengths of the triangle itself instead of going with semiperimeter i.e.

** Area = 0.25 * √((a + b + c) * (-a + b + c) * (a - b + c) * (a + b - c))**

**Two sides and the angle between them (SAS)**

You can find the area of the triangle easily using trigonometric laws when you are given two sides and one angle.

** Area = 0.5 * a * b * sin(γ)**

γ is the angle between the sides a and b.

**Two angles and a side between them (ASA)**

You can use this formula when you are given one side and two angles.

** Area = = a² * sin(β) * sin(γ) / (2 * sin(β + γ))**

γ and β are the angles along the given side a.

**Example **

Calculate the area of a triangle if the base and height are 4cm and 5cm respectively?

**Solution: **

The basic formula to find the Area of Triangle = **(1/2)bh**

Given Base = 4 Cm

Height = 5 Cm

Substitute the given values in the formula and on doing so we will get it as such

Area of Triangle = (1/2)4*5

= 0.5*4*5

**= 10 cm2**
