A Scalene triangle contains three unequal sides and three unequal angles.

A Scalene triangle is that triangle which have three singled-out sides and also three distinct angles.

Differences	Scalene	Isosceles	Equilateral
Sides	Have 3 sides with different lengths	2 Sides of the triangle are equal	3 sides of a triangle are Equal
Angles	Have iii unlike angles	It has One Angle which is equal to 90 (Right Angle)	iii Angles of this triangle are Equal

Area of Scalene Triangle Formula

1. The length of 1 side and the normal or perpendicular altitude of that side to the angle which is opposite to that side.
2. The lengths of every sides.

Area of Scalene Triangle with Base of operations and Meridian

The area of a scalene triangle with whatever side every bit base 'B' and height 'H' is given by;

A = (i/2) 10 B 10 H square units.

For example:

Determine the expanse of the triangle having base equals to 20 cm and height equals to 12 cm.

Solution: Base = B = 20 cm

Summit = H = 12cm

A = (i/ii) x B 10 H

A = 12 x 20 x 12

A = 120 cmⁱⁱ

Area of Scalene Triangle Using Heron's Formula

Step 1: If we have the length of three sides of a triangle (a, b, c).

Footstep 2: Calculate the semi-perimeter of the triangle, S.

Therefore,

southward = (a + b + c) / 2

Step iii: Then use Heron'southward formula to calculate the area of a scalene triangle.

Area of a Scalene Triangle with 3 Sides

Calculate the area of a triangle having sides 122 cm, 120 cm, and 22 cm.

Solution:

s = (a + b + c) / 2
