What is the formula of triangles area?
Area of a Triangle - How to Find Area of triangle | Formulas ...
Area of a Triangle = A = ½ (b × h) square units

where b and h are the base and height of the triangle, respectively. Now, let's see how to calculate the area of a triangle using the given formula.

What is the area of a triangle with 3 sides?
Area of Triangle with 3 Sides - Formula, Proof, Examples
Heron's formula is used to find the area of a triangle that has three different sides. Heron's formula is written as, Area = √[s(s-a)(s-b)(s-c)], where a, b and c are the sides of the triangle, and 's' is the semi-perimeter of the triangle.

How to find the sides of a right triangle
If leg a is the missing side, then transform the equation to the form where a is on one side and take a square root: a = √(c² - b²)
If leg b is unknown, then: b = √(c² - a²)
For hypotenuse c missing, the formula is: c = √(a² + b²)
