Find area of triangle with 3 sides calculator

Let us learn how to find the area of triangle with 3 sides given; that is when the length of three sides of a triangle is given. The area of a two-dimensional, closed geometric figure is the amount of region enclosed by that figure. It is expressed in terms of square units. Generally, we find the area of a triangle by halving the product of base and height. The area of triangle with 3 sides was first derived by the Greek mathematician Heron of Alexandria. He gave a formula which could calculate the area of a triangle without any requirement of measure of angles or any other distances, rather than the length of the sides of the triangle. Let us recall the law of cosines for any given triangle. According to the rule, the square of any side is equal to twice the product of the other two sides with the cosine of the angle in between them, subtracted from the sum of the square of the other two sides. Find the area of an isosceles triangle whose equal sides are of length 9 cm, and the third side is 12 cm. The semi-perimeter of an isosceles triangle is 15 cm, and the length of the unequal side is 12 cm. Find the length of the other two sides and the area of the triangle.

The area of triangle with 3 sides was first derived by the Greek mathematician Heron of Alexandria. A triangle is usually referred to by its vertices.

This triangle area calculator can help in determining the triangle area. The basic triangle area formula needs to have a base and height given, but what if we don't have it? How can we calculate the area of a triangle with 3 sides only? The triangle area calculator is here for you. Give it a go! If you are still unsure how to find the area of a triangle, check the description below.

Instructions: Use this triangle calculator with three sides known to determine a triangle completely. Please provide the three sides of the triangle:. A triangle calculator will help you find all the parameters of a triangle, knowing only some initial information about the triangle. Indeed, a triangle has 3 angles and 3 sides when it is completely determined, and using different trigonometric and geometric properties, it is enough to know three of those parameters in order to determine the other three. But it is not just any three pieces of information. You have to have either: two sides and an angle, or two angles and a side or you need to have three sides. This calculator shows how to work out the case when know you the three sides. For example, having the three angles of a triangle is not enough to determine the sides.
