How to find the Area of a Triangle - mathwarehouse
WebSep 6, 2024 · To find the total area, multiply the area of the smaller triangle by 10. In our example, the area of the whole pentagon = 8.4 x 10 = 84 square units. Method 3 Using a Formula 1 Use the perimeter and apothem. The apothem is a line from the center of a pentagon, that hits a side at a right angle. WebA scalene triangle is a triangle with 3 different side lengths and 3 different angles. The area of a scalene triangle can be calculated using Heron’s formula. Heron’s formula is given by; ⇒ Area = √ {p (p – a) (p – b) (p – c)} where ‘p’ is the semi-perimeter and a, b, c are the side lengths. ⇒ p = (a + b + c) / 2 Example 7 eastern hose onsite ltd
