Understanding Triangle Perimeter
The perimeter of a triangle is the total distance around its sides. To find the perimeter, you simply add the lengths of all three sides: side a, side b, and side c.
Formula: Perimeter (P) = a + b + c
For example, if a triangle has sides of length 3, 4, and 5 units, its perimeter would be 3 + 4 + 5 = 12 units.
This calculator makes it easy to quickly determine the perimeter of any triangle, which is useful in various fields such as construction, engineering, and everyday problem-solving.
