How To Find Area Of A Scalene Triangle
Area of Scalene Triangle
The total surface area of a scalene triangle is the expanse betwixt the boundaries of the scalene triangle. A scalene triangle is a special type of triangle where all three sides of the triangle are of different lengths as well as the angles are of unlike measures. Although all the angles of a scalene triangle are different the sum of all the interior angles of the triangle is still 180 degrees. We will discuss the area of the scalene triangle, the formula for computing the area along with the solved examples, and a few practice questions in the end.

What Is the Area of Scalene Triangle?
The area of a scalene triangle tin be defined every bit the amount of space covered by a flat surface inside the scalene triangle. It is measured every bit the "number of" square units (square centimeters, square inches, square feet, etc.).
Surface area of a Scalene Triangle Formula
The formula of the area of the scalene triangle is used to observe the surface area occupied past the scalene triangle within its purlieus. The area of the scalene triangle is obtained by taking half of the product of the base to the height of the triangle. Thus, the formula for the area of the scalene triangle, with a base "b" and pinnacle "h" is "(1/2) bh".
Or, Area of a Scalene Triangle = [(one/two) × base × height] foursquare units
Calculation of Area of a Scalene Triangle
As the triangle has 6 quantities namely 3 sides and three angles, the area of a triangle is calculated via various formulas depending upon the known quantities of the triangle.
-
Area of Scalene Triangle With Base and Height
When the base and tiptop of the scalene triangle is known, and so the area of a triangle is:
Area of a triangle = (1/ii) × Base × Height
where b and h are the base of operations and top of the triangle respectively.
-
Surface area of Scalene Triangle Using Heron'south Formula
Heron's formula is applicative when all three sides of the triangle are known to the states.
Consider the triangle ABC with sides a, b, and c has shown in the image.
Heron'south formula is: \(\text{Expanse} = \sqrt{due south(s-a)(s-b)(due south-c)}\)
where, a, b, c are the side length of the triangle, and, s is the semi-perimeter and equals (a+b+c)/2.
-
Expanse of the Scalene Triangle With 2 Sides and Included Angle (SAS)
We can observe the scalene triangle'due south area when the length of its ii sides and the included angle are given.
1. When two sides b and c and included angle A is known, the area of the triangle is, Area = (ane/2) bc × sin A
2. When sides a and c and included angle B is known, the area of the triangle is, Expanse = (1/ii) ac × sin B
iii. When sides a and b and included angle C is known, the area of the triangle is, Expanse = (1/2) ab × sin C
List of Surface area of Scalene Triangle Formula List
The area of a triangle can be calculated using the formulas discussed higher up. Here is a listing of all those formulas:
| Area of the ScaleneTriangle When | Formula |
|---|---|
| Base and height of a triangle are given | (one/2) × base × height |
| Sides of a triangle are given | \(\sqrt {south(s - a)(s - b)(due south - c)} \) where a, b, c are the sides and s is the semi-perimeter, s = (a+b+c)/ii |
| Ii sides and the included angle are given | \(\dfrac{1}{2}\: {\text{side}_1} \times {\text{side}_2} \times \sinθ\) where 'θ' is the angle between the given two sides. |

FAQs on Area of a Scalene Triangle Formula
What Is the Area of a Scalene Triangle and the Perimeter of the Scalene Triangle in Math?
The surface area of a figure is the region enclosed by the scalene triangle. The perimeter of a scalene triangle is the total length of the purlieus of the effigy.
What Is the Formula to Calculate Surface area of Scalene Triangle?
The area of the scalene triangle can be calculated using different formulas,
- Using base and height: (one/ii) × base × meridian
- Using Heron'southward formula: \(\sqrt {s(southward - a)(due south - b)(southward - c)} \), where where a, b, c are the sides and south is the semi-perimeter, s = (a + b + c)/two.
- Using Trigonometry: \(\dfrac{1}{2}\: {\text{side}_1} \times {\text{side}_2} \times \sinθ\), where 'θ' is the angle between the given two sides.
How Do You Notice the Area of a Scalene Triangle?
The area of a triangle can be calculated by applying different formulas depending upon the known parameters.
- The expanse of the scalene triangle can be calculated using the base and superlative past finding one-half of the product of the base and the height of the scalene triangle.
- Given the measure of iii sides of the scalene triangle, Heron's formula can be used to discover the area of the scalene triangle, A \(\sqrt {s(due south - a)(s - b)(south - c)} \), where a, b, c are the sides and s is the semi-perimeter, s = (a + b + c)/2.
- We can summate the area of scalene triangle when the two sides and the included angle are given as, Area = \(\dfrac{1}{two}\: {\text{side}_1} \times {\text{side}_2} \times \sinθ\), where 'θ' is the angle betwixt the given two sides.
How Practise You Notice the Area of a Scalene Triangle Without Height?
Heron's formula can be used to find the area of a triangle when the length of the 3 sides of the triangle is known. Hence, the area of the triangle can be calculated using Heron's formula without using height. The formula to calculate surface area in this instance is given as, A = \(\sqrt {s(s - a)(s - b)(southward - c)} \), where 's' is the semi-perimeter.
