What is the formula for finding the perimeter of an equilateral triangle?

Perimeter of equilateral triangle = 3a and semi-perimeter of an equilateral triangle = 3a/ 2, where a is the side. Given a = 12 units. Therefore, the perimeter of equilateral triangle = 3 × 12 = 36 units and Semi-perimeter of an equilateral triangle = 36/2 = 18 units.

How do we find the perimeter of triangle?

What Is the Formula of Perimeter of Triangle? The perimeter of a triangle can be calculated by simply adding the length of all the sides. The basic formula to calculate the perimeter of a triangle with sides ‘a’, ‘b’, and ‘c’ is: a + b + c.

What is the area and perimeter of an equilateral triangle?

How Do You Find the Perimeter and Area of an 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 formula of equilateral?

In general, the height of an equilateral triangle is equal to √3 / 2 times a side of the equilateral triangle. The area of an equilateral triangle is equal to 1/2 * √3s/ 2 * s = √3s2/4.

What is the perimeter of ∆ ABC?

Perimeter of Δ ABC = Length of AB + Length of BC + Length of AC. Perimeter of Δ ABC = 24 units.

What is perimeter and its formula?

As we already know, the perimeter is the length of the sides or boundary or path of a shape. The perimeter formula of a square can be calculated by adding the length of all its sides. The formula to calculate the perimeter of a square can be given as, Perimeter of a Square, (P) = 4 × Side units.

What is the area and the perimeter?

Perimeter is the distance around the outside of a shape. Area measures the space inside a shape.

How do you find perimeter with height?

The perimeter is the sum of all sides of a figure to get one length. So, to find the perimeter, the formula is base + height + base + height. If the base is 10 inches and the height is 5 inches, you would have: Perimeter: 10 + 5 + 10 + 5 = 30 inches.

Where is perimeter used?

We often find the perimeter when putting up Christmas lights around the house or fencing the backyard garden. Other examples may include finding the total length of the boundary of the soccer field or the length of the crochet or ribbon required to cover the border of a table mat.

What is the formula for finding area of rhombus?

The area of a rhombus is equal to half the product of the lengths of the diagonals. The formula to calculate the area of a rhombus using diagonals is given as, Area = (d1 d 1 × d2 d 2 )/2 sq. units, where, d1 d 1 and d2 d 2 are the diagonals of the rhombus.

What is the formula for the height of a triangle?

There are two different heights of an isosceles triangle; the formula for the one from the apex is: hᵇ = √ (a² – (0.5 * b)²), where a is a leg of the triangle and b a base. The formula is derived from Pythagorean theorem The heights from base vertices may be calculated from e.g.

What is the equation for a triangle?

A triangle is one of the most basic shapes in geometry. The best known and the simplest formula, which almost everybody remembers from school is: area = 0.5 * b * h, where b is the length of the base of the triangle, and h is the height/altitude of the triangle.

What is the height of an equilateral triangle?

An equilateral triangle has a side of 16 units. What is the height of this equilateral triangle. 16/2=8√3 units or 13.856 units. The height of an equilateral triangle is 10 units.

What is the formula for the area of an equilateral?

If we know the side of an Equilateral Triangle then, we can calculate the area of an Equilateral Triangle using below formula. Area = (√3)/4 * s² (S = Any side of the Equilateral Triangle) Perimeter is the distance around the edges.
