# By heron's formula area of triangle is?

Asked by: Kimberly Richards  |  Last update: 18 June 2021

Another is Heron's formula which gives the area in terms of the three sides of the triangle, specifically, as the square root of the product s(s – a)(s – b)(s – c) where s is the semiperimeter of the triangle, that is, s = (a + b + c)/2.

Regarding this, Which of the following is the Heron's formula to find the area of a triangle of side a B and C and semi-perimeter s?

Hence, area of a triangle by heron's formula is A=s(s−a)(sb)(sc) ​.

Simply so, How do you use Heron's area formula?. Use Heron's formula to find the area of triangle ABC, if AB=3,BC=2,CA=4 . Substitute S into the formula. Round answer to nearest tenth. Since Heron's formula relates the side lengths, perimeter and area of a triangle, you might need to answer more challenging question types like the following example.

Moreover, What is Heron's formula?

In geometry, Heron's formula (sometimes called Hero's formula), named after Hero of Alexandria, gives the area of a triangle when the length of all three sides are known. Unlike other triangle area formulae, there is no need to calculate angles or other distances in the triangle first.

Why we use Heron's formula?

Heron's formula is used to find the area of a triangle when we know the length of all its sides. It is also termed as Hero's Formula. We don't have to need to know the angle measurement of a triangle to calculate its area.

### Does Heron's formula work for all triangles?

Heron's formula is used to determine the area of triangles when lengths of all their sides are given or the area of quadrilaterals. We also know it as Hero's formula. This formula for finding the area does not depend on the angles of a triangle. It solely depends on the lengths of all sides of triangles.

### Is Heron's Formula accurate?

Heron's formula computes the area of a triangle given the length of each side. If you have a very thin triangle, one where two of the sides approximately equal s and the third side is much shorter, a direct implementation Heron's formula may not be accurate.

### Who found Heron's formula?

Heron's formula, formula credited to Heron of Alexandria (c. 62 ce) for finding the area of a triangle in terms of the lengths of its sides.

### What is the area of the triangle?

The area of a triangle is defined as the total region that is enclosed by the three sides of any particular triangle. Basically, it is equal to half of the base times height, i.e. A = 1/2 × b × h.

### How do you prove Heron's formula using trigonometry?

Proof. The following proof is trigonometric, and basically uses the cosine rule. First we compute the cosine squared in terms of the sides, and then the sine squared which we use in the formula A=1/2bc·sinA to derive the area of the triangle in terms of its sides, and thus prove Heron's formula.

### Can you use Heron's formula for right angle triangle?

Area of the right angled triangle can be calculated by two ways that id with the help of half of height multiplied by base formula and we can also calculate the value of the area using heron's formula. In heron's formula, Area =√s(s−a)(s−b)(s−c) where s is the sum of all the sides of a triangle divided by 2.

### What is the area of the right triangle?

Area of Right Triangle Formula

So the area of a right triangle is obtained by multiplying its base and height and then making the product half. The area of a right triangle with base 6 cm and height 4 cm is 1/2 × 6 × 4 = 12 cm2.

### Who invented area?

In the 5th century BCE, Hippocrates of Chios was the first to show that the area of a disk (the region enclosed by a circle) is proportional to the square of its diameter, as part of his quadrature of the lune of Hippocrates, but did not identify the constant of proportionality.
