What is the perimeter of an equilateral triangle?
It is the sum of the lengths of the three sides. However, since all three sides are of the same length, the perimeter equals three times the length of any one side.
How do you find the perimeter of a equilateral triangle?
you multiply one of the sides by three. The perimeter is the total length of the outside of the shape - in this case the total of the lengths of the three sides. You'll need to know the length of one side and an angle to calculate the lengths of the others in any triangle, however in an equilateral triangle all the sides are the same length so if you know one you know them all.
Perimeter formula of a triangle?
The perimeter formula of a triangle is the sum of the lengths of all three sides. Mathematically, it can be expressed as P = a + b + c, where P is the perimeter and a, b, and c are the lengths of the three sides of the triangle.
