If the sides of a triangle are given along with an included angle, the area of the triangle can be calculated with the formula, Area = (ab × sin C)/2, where 'a' and 'b' are the two given sides and C is the included angle. What is the Area of a Triangle with three Sides and an Angle? For example, if the height (altitude) of a triangle = 8 units, and the side of the triangle on which the altitude is formed is given (base) = 7 units, we can find its area using the formula, Area of a triangle = 1/2 × base × height. Area of a triangle = 1/2 × base × height. If we know the sides of a triangle along with its height, we can use the basic formula for the area of a triangle. What is the Area of Triangle with 3 Sides and Height? For example, if an equilateral triangle has a side of 6 units, its area will be calculated as follows. The area of an equilateral triangle can be calculated using the formula, Area = a 2(√3/4), where 'a' is the side of the triangle. If a triangle has 3 equal sides, it is called an equilateral triangle. 's' be calculated as follows: semi perimeter = (a + b + c)/2 What is the Area of Triangle with 3 Sides Equal Sides? The area of a triangle with 3 sides can be calculated with the help of the Heron's formula according to which, the area of a triangle is √, where a, b, and c, are the three different sides and 's' is the semi perimeter of the triangle. \( \begin\)įAQs on Area of Triangle with 3 Sides What is the Area of a Triangle With 3 Sides? Using one of the Trigonometric identities, Using law of cosines, cos A = (b 2 + c 2 - a 2) / 2bc. The proof of the formula for the area of triangle with 3 sides can be derived in the following way.Ĭonsider the triangle shown above with sides a, b, c, and the opposite angles to the sides as angle A, angle B, angle C. How to Find Area of Triangle with Three Sides? Proof of Area of Triangle with 3 Sides Formula This formula was derived by a Greek mathematician known as the Heron of Alexandria. However, if the altitude of a triangle is not known, and we need to find the area of triangle with 3 different sides, the Heron's formula is used. The basic formula that is used to find the area of a triangle is ½ × Base × Height where "Base" is the side of the triangle on which the altitude is formed, and "Height" is the length of the altitude drawn to the "Base" from its opposite vertex. The area of a triangle can be calculated with the help of various formulas. Using this, the area of a triangle (A) with 3 sides a, b, and c is calculated using the formula A = √, where 's' is the semi-perimeter of the triangle given by s = (a + b + c)/2.
