Jul 30, 2024 · If you know the lengths of all sides (a, b, and c) of a triangle, you can compute its area: Calculate half of the perimeter ½(a + b + c). Denote this value by s. Compute s - a, s - b, and s - c. Multiply the three numbers from Step 2. Multiply the result by s. Take the square root of the result.

The formula for the area of a triangle is side x height, as shown in the graph below: There are different starting measurements from which one can solve a triangle, calculate the length of a side and height to it, and finally calculate a triangle's area. There are 4 common rules for solving a triangle, as explained below.
Aside from the basic formula of side x height, we have the SSS, ASA, SAS, and SSA rules for solving a triangle, where S is a side length and A is the angle in degrees. The abbreviations denote our starting measurements. Our area of triangle calculator supports the basic formula, these four rules, and the hypotenuse and the length of one of the othe...
So, how to calculate the area of a triangle using more advanced rules? You can solve the whole triangle starting from different sets of measurements: 1. SSS (side-side-side)- you basically have all three sides, from which you can calculate the angles, and from there - the height, using the Pythagorean theorem. 2. SAS (side-angle-side)- having the l...
Example 1: Using the illustration above, take as given that b = 10 cm, c = 14 cm and α = 45°, and find the area of the triangle. In this case the SAS rule applies and the area can be calculated by solving (b x c x sinα) / 2 = (10 x 14 x sin(45)) / 2 = (140 x 0.707107) / 2 = 99 / 2 = 49.5 cm2. Example 2: If one side of the triangle is known to be 6 ...
An everyday use of triangle math is if you want to lay tiles at perfect 90° or 45° to the sides of a room. The reference lines are established using the 3-4-5 rule. If you want to know how long a ladder should be so it can reach a given height at a given angle with the ground. Steel and wooden structures like houses, bridges, warehouses, etc. often...
Where a and b are two sides of a triangle, and c is the hypotenuse, the Pythagorean theorem can be written as: a 2 + b 2 = c 2. EX: Given a = 3, c = 5, find b: 3 2 + b 2 = 5 2 9 + b 2 = 25 b 2 = 16 b = 4. Law of sines: the ratio of the length of a side of a triangle to the sine of its opposite angle is constant.
Area of a triangle. The formula for the area of a triangle is height x π x (radius / 2) 2, where (radius / 2) is the radius of the base (d = 2 x r), so another way to write it is height x π x radius 2. Visual in the figure below: Despite the simplicity of the above equation, in specific situations you may not know these two exact measurements.
Using the formula, Area of a Triangle, A = 1/2 × b × h. = 1/2 × 4 (cm) × 3 (cm) = 2 (cm) × 3 (cm) = 6 cm 2. Apart from the above formula, we have Heron’s formula to calculate the triangle’s area when we know the length of its three sides. Also, trigonometric functions are used to find the area when we know two sides and the angle ...
Solution : The given values base b = 18 cm height h = 12 cm Step by step calculation formula to find area = (1/2) b h = (1/2) x Base x Height substitute the values = (1/2) x 18 x 12 = 108 cm2 The area of a triangle may required to be calculated in SI or metric or US customary unit systems, therefore this triangle area calculator is featured ...

To calculate the area of a triangle, there are three main formulas that are commonly used. The first one is the `base and height` formula, which is used when the base and height of the triangle are known. The formula for this: S = \dfrac {ah} {2} S = 2ah. where S is the triangle area, a is the base and h is the height of the triangle.
