# 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 cm^{2}

= 14 cm^{2}

** 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 cm^{2}

= 110.5 cm^{2}
