In an equilateral triangle, all three sides are equal in length. The area of a Triangle is defined as the total region that is enclosed by the three sides of an equilateral triangle. The area of the triangle is the space covered by the triangle in a two-dimensional plane. Basically they will give us the position vectors of the corresponding sides. First, the value of s is found which is equal to (a+b+c)/2; Then, the Heron's formula is applied to determine the area of the triangle formed by all three sides. All you need is the base and the height of the triangle. Surface Area of Triangular Pyramid Formulab is the side of the triangle pyramid.a is the height of the base triangles is the slant height of a triangular pyramid.12 (a b) is the base area of the triangular faces.32 (b s) is the product of the perimeter and slant height of a pyramid. Slope of CA . Its area is calculated by the formula A = 3a^2 /4 where A is the area of an equilateral triangle and a is the side of an equilateral triangle. In Geometry, a triangle is a three-sided polygon that has three edges and three vertices. Now, let us learn to calculate the area of a triangle whose coordinates of the vertices are given. The formula for the area of a triangle is (1/2) base altitude. If they are the position vectors of the ABC then the area of the triangle will be written as.
