# Scalene Triangle Formula

## What is Scalene triangle ?

If a triangle has 3 unequal sides and also the angles of the triangle are different then it is called a Scalene triangle.

## Properties of Scalene triangle

• 3 unequal sides
• 3 unequal angles
• Line of symmetry missing.

## Formula for Scalene triangle

 Area of Triangle = ½ x b x h Where b is base and h is the height. When all sides are given, Area  $$=\sqrt{s(s-a)(s-b)(s-c)}$$ Where s = semiperimeter (a+b+c)/2

Both the above formulas can be used to find the area of scalene triangle depending on whether the three sides of the triangle are given or not.

## Example of Area of a scalene triangle formula

If the base of a triangle is 6 and height is 10 cm, Find the area of the scalene triangle?

Solution:

Area of Triangle = ½ x b x h

Where b is base, h is the height.

A = ½ X 6 X 10

= 30cm2
