How to find the surface area of an equilateral triangle?

An equilateral triangle has three sides of equal length. The length of each side is equal to the length of the hypotenuse. The sides of an equilateral triangle are also equidistant from one another. In order to find the surface area of an equilateral triangle, you need to know the length of each side of the triangle. The surface area of an equilateral triangle is equal to 1/2 base x height. The base is equal to the length of the hypotenuse.

How to find the surface area of an equilateral triangle without calculator?

Using the Pythagorean theorem, we can easily calculate the area of an equilateral triangle and find an approximate value based on the sides of the triangle. This is a great method for those who do not have access to a calculator and want to learn how to find the surface area of an equilateral triangle without calculator.

How to find the surface area

First, you’ll need to find the perimeter of the triangle. This is the sum of the three sides. If you have a triangle drawn out, you can use the Pythagorean Theorem to find the perimeter. The Pythagorean Theorem states that the sum of the squares of the legs equals the square of the hypotenuse. Therefore, the perimeter of an equilateral triangle is sqrt(3) × side length.

How to find the surface area of an equilateral triangle with perimeter?

The surface area of an equilateral triangle with sides of length P is given by P^2/6. To find the surface area of an equilateral triangle with sides of length P given any perimeter, just divide the perimeter by π. For instance, if the perimeter is 15, the surface area of the triangle is 15/π ≅ 4.3.

How to find the surface area of an equilateral triangle with parallel sides?

To find the surface area of an equilateral triangle with sides of length a, you need to know the length of each of its sides. We will use the Pythagorean theorem to find the length of each side. The Pythagorean Theorem states that the sum of the squares of the legs of a right triangle is equal to the square of the hypotenuse. For our equilateral triangle with sides of length a, its hypotenuse will be one unit and its legs will be a
