# Formula for the Area of a Triangle

The amount of space a triangle occupies is its area. A triangle is a geometric shape with three sizes - the length of each side can be different or same. When all three sides of a triangle are of equal length, it's an equilateral triangle, whereas you have an isosceles triangle if two of its sides are equal in length.

Area of a Triangle Formula is,

Area of triangle = $\frac{1}{2}bh$

Where

b is the base of the triangle.

h is the height of the triangle.

Area of a Triangle Problems

Some solved problems on area of a triangle are given below:

Solved Examples

Question 1:  Find the area of a triangle of base 4 cm and height 7 cm?

Solution:

Given,

b = 4 cm

h = 7 cm

Area of a triangle

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

= $\frac{1}{2}$ * 4 * 7 cm2

= 14 cm2

Question 2:  Find the area of a triangle of base 18 cm and height 25 cm?

Solution:

Given,

b = 18 cm

h = 25 cm

Area of a triangle

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

= $\frac{1}{2}$ * 13 * 17 cm2

= 110.5 cm2
