Heron's Formula Example For a triangle with sides a = 4, b = 3, and c = 5: s = (4+3+5)/2 s = (12)/2 s = 6 Then use the second part of Heron's formula, Area = … WebPerimeter of a triangle formula The formula for the perimeter of a triangle T is T = side a + side b + side c, as seen in the figure below: However, given different sets of other values about a triangle, it is possible to calculate the perimeter in other ways.
WebHow do you work out the area of a triangle? Area of a triangle. To calculate the area of a triangle, multiply the height by the width (this is also known as the 'base') then divide by 2. WebJan 31, 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. This is the area of your triangle - well done!
