IntroductionIn this lesson, we will learn how to calculate the area of triangles. This is very easy and quick topic as long as you know the formula for finding the area of a triangle. So, let's review the formula and get started!
Formula for Area of Triangleb x h x 1/2
Area of TriangleLet's say we have a triangle with the following measurements:
In order to find the area of the above triangle, we need to multiply 12 x 10 x 1/2
12 x 10 equals 120 x 1/2 equals 120/1 x 1/2 equals 120/2 equals 60.
The area of the triangle equals 60 inches to the power of 2.
