Formula for Area of a TriangleFormula 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 al 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 al the sides are not equal in
length. In the scalene triangle all the sides and angles are of different size in length and
measure.Know More About :- Second Derivative Test Math.Tutorvista.comPage No. :- 1/4
(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 * bLearn More :- Quotient Rule Derivative Math.Tutorvista.comPage No. :- 2/4
= 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 Math.Tutorvista.comPage No. :- 4/4
