### What is the perimeter of an equilateral triangle with one side measuring 4x 8 units?

Since the triangle is equilateral, every side is congruent to one another. Thus the perimeter is 3(S), with S being the length of a side.

**What is the perimeter of equilateral?**

3a

Because the sides of the equilateral triangle are equal, the perimeter is equal to 3a.

**What is the perimeter of a b c?**

The perimeter of a scalene triangle can be calculated by finding the sum of all the unequal sides. The formula for the perimeter of a scalene triangle is: Perimeter = a + b + c, where “a”, “b”, and “c” are the three different sides.

## What is the area and perimeter of the equilateral triangle?

The area of an equilateral triangle is √3/4 times (side)2 of the equilateral triangle and the perimeter of an equilateral triangle is 3 times of a side of the equilateral triangle.

### What is the perimeter of the formed triangle?

The perimeter of a triangle is the sum of lengths of its sides. The three vertices of the given triangle are O(0, 0), A(a, 0) and B(0, b). Let us now find the lengths of the sides of the triangle. Thus the perimeter of the triangle with the given vertices is `a + b + sqrt(a^2 + b^2)` .

**What is the formula for finding the perimeter of a triangle?**

Instructions for finding the perimeter of a triangle. The perimeter of a triangle is found by adding the length of all three sides of the triangle. The formula. P = a + b + c. An example of finding the perimeter of a triangle using “in” for inches as the measure for each side. a = 2 in. b = 2 in.

**What does the perimeter have to equal in a triangle?**

Perimeter is the sum of all the sides of a closed figure. An equilateral triangle is a triangle having all three sides equal in length. Perimeter of equilateral triangle is equal to three times the length of a side of a triangle. Perimeter of Equilateral Triangle = 3 x Length of each side

## How do you find the sides of an equilateral triangle?

If you’re trying to find a side other than the hypotenuse, square the side given, subtract it from the hypotenuse squared, and take the square root of the answer. Recognize that an equilateral triangle has three equal sides.

### What are the identifying features of an equilateral triangle?

Identifying equilateral triangles. An equilateral triangle has three equal sides and three equal angles (which are each 60°). Its equal angles make it equiangular as well as equilateral.
