# Scalene Triangle Area Calculator

Triangles are ubiquitous in geometry, but you're in the right place if you're looking for something about scalene triangles particularly. **Scalene triangle area calculator will help you find the area of the figure no matter what data you have given.** Sides? Angles? Height and base? – we've covered them all with special scalene triangle area formulas. Read on and get to know more about triangles!

## What is a scalene triangle?

A scalene triangle is a triangle with **three sides, all of different lengths**. There are no two or three sides of the same length in a scalene triangle.

## Using scalene triangle area calculator

Using our tool is simple & intuitive!

- In the first row,
**choose the mode**you want to work in. It depends on which data about your triangle you know. - Let's assume we
**know the three sides**, so we choose the mode**three sides SSS (**.*side-side-side*) - Under the triangle image, we can see three empty fields. Input the lengths of the sides.
- Our calculator works automatically and gives you the answer right away.
- To use a different mode, just
**choose it in the first row**. No need to clear the data. - Now you know how to use the scalene triangle area calculator!
- Remember that
**all the scalene triangle area formulas are available in the text below in case you need them.**

## How do I find the area of the scalene triangle? – formulas

There are four ways to find the area of a scalene triangle. The use depends on which data you have given.

Scalene triangle area formulas with known:

**Base ($b$) and height ($h$)**

**Three sides ($a$, $b$, $c$)**

**Two sides and the angle between them (sides – $a$, $b$; angle – $\gamma$)**

**Two angles ($\gamma$, $\beta$) and a side between them ($a$)**

## FAQ

### Are all scalene triangles acute?

**No, not all scalene triangles are acute.** A scalene triangle might be right, acute, or obtuse.

### How do I calculate the scalene triangle area?

To calculate the scalene triangle area, use one of these equations:

**area = 0.5 × b × h**, where**b**– the base,**h**– height.**area = 0.25 × √[(a + b + c)(-a + b + c)(a - b + c)(a + b - c)]**, where**a**,**b**,**c**– triangle's sides.**area = 0.5 × a × b × sin(γ)**, where**a**,**b**- sides;**γ**– an angle between those sides.**area = a² × sin(β) × sin(γ) / (2 × sin(β + γ))**, where**β**,**γ**– angles,**a**– side between those angles.

### How do I find the area of the scalene triangle with sides 3, 5, 7 inches?

The area of this triangle is **6.495 in ^{2}**. To find the triangle area with three sides:

- Use Heron's formula:

**area = 0.25 × √[(a + b + c)(-a + b + c)(a - b + c)(a + b - c)]** - Knowing all three
**a**,**b**,**c**, solve the equation. - The answer is
**6.495 in**.^{2}

### How many sides are equal in a scalene triangle?

There are no equal sides in a scalene triangle. A scalene triangle is a triangle **with three unequal sides.**
