# Area of a Triangle Formula

Triangle usually comprises of three edges and three vertices. Classified into three different types of triangles i.e. Equilateral, Isosceles and Scalene – each triangle has its own unique features and properties. If all three angles of a triangle are equal, the triangle is called Equilateral. A Isosceles triangle has two equal angles. A Scalene triangle is one in which all three angles are different. A right triangle has one right angle. In Geometry, two triangles are congruent if they are of the same shape and size.

**Area of a Triangle Formula**is,

**$\frac{1}{2}$ah**

Where,

a is the base of the triangle.

h is the height of the triangle.

### Solved Examples

**Question 1:**Find the area of an obtuse triangle with a base of 5 inches and a height of 8 inches.

**Solution:**

Given,

b = 5 in

h = 8 in

Area of a triangle

= $\frac{1}{2}$ bh

= $\frac{1}{2}$ * 5 * 8 in

h = 8 in

Area of a triangle

= $\frac{1}{2}$ bh

= $\frac{1}{2}$ * 5 * 8 in

^{2 }= $\frac{40}{2}$ in^{2 }= 20 in^{2}More topics in Area of a Triangle Formula | |
