Formula for Area of a Triangle Formula for Area of a Triangle In the geometry, a triangle can be consider as a one of the most basic shape that has three sides which are interlinked with each other to form a closed shape. A triangle can be consider as a polygon that has three vertices and the three sides that are most popularly known as edges of the polygon. In the mathematical definition w e can say that a triangle is a geometrical shape that has three straight lines which are interlinked with each other to form a closed shape. On the basis of the three sides of the triangle we can categorize the triangle into three types. The three types of triangles are given below: (A) Equilateral triangle: Equilateral triangle is a type of triangle that has all the sides equal in length. An equilateral triangle can be considered as a regular polygon. (B) Scalene triangle: Scalene triangle is a type of triangle where all the sides are not equal in length. In the scalene triangle all the sides and angles are of different size in length and measure.

(c) Isosceles Triangle: It is a special type of a triangle where two sides of the triangle are equal in length. In the same aspect we can say that the two angles of the triangle have the same measure in size. Here we are going to discussing about the Formula for Area of a Triangle to calculate the area of the triangle. To find the area of the triangle we need to perform the product of base and height of the triangle and perform division by two. In the mathematical formula notation we can represent the formula for calculating the area of rectangle as: Formula for Area of a Triangle = 1 / 2 * h * b In the above notation we use the symbol ‘h’ as the height of the triangle. In the same aspect the symbol ‘b’ is used for representing the value of base of the triangle. Here we need to remember one thing that the value of base and height must be perpendicular to each other. Now we show you some of the example that helps in understanding the concept of calculating the area of rectangle. Example a: Suppose Donald has a mat which is in shape of triangle. The base of the mat is 15 inches and the height of the mat is 10 inches. Donald wants to perform the decoration on the mat, which required the cost of $ 2 @ of per inches square. What will be the total cost of developing a mat? Solution: In the above question given that Donald has triangular mat which has the base of a5 inches and the height of the mat is 10 inches. Through the given value we can easily calculate the area of rectangle is: Area of triangular mat is = 1 / 2 * h * b

= 1 / 2 * 15 * 10 = 75 inches2 On the basis of given area of the triangular mat we can easily calculate the total cost of developing a mat is 75 inches2 * $ 2 So, the total cost is = $ 150
