Area of a Triangle

This video helps to find the area of a triangle. The lesson is designed for children at the elementary level for 6-12 years of age. 

We can also calculate the area of the triangle using squares. Want to know how? Watch this video

We recommend that your child explore this practical method to find the area of a triangle for easy understanding.

What is the area of a triangle?

The area of a triangle is defined as the area (total region) that is enclosed by the three sides of the triangle. It is equal to half of the base times height, i.e. A = 1/2 × b × h. Hence, to find the area of a triangle, we need to know its base (b) and height (h) of it. The unit of area is measured in square units.

How to Calculate the Area of a Triangle?

Let us learn how to calculate the area of a triangle with the below example:

Area of a triangle = 1/2(b*h) (half * base* height)

Let the base of a triangle be: 10 meters and the height be: 10 meters

Then, the area of the triangle will be 1/2*b*h

=1/2 *10*10


=50 square meters
