Understanding the Area of a Triangle and Solving for Height

The video tutorial explains the formula for the area of a triangle, A = 1/2 * b * h, where A is the area, b is the base, and h is the height. It then demonstrates how to solve this formula for the height by isolating h on one side of the equation. The process involves multiplying both sides by 2 to eliminate the fraction and then dividing by the base to solve for h. The tutorial provides a visual representation of a triangle to clarify the concepts of base and height.

What is the formula for the area of a triangle?

• A = 2 b h

• A = b h

• A = b + h

• A = 1/2 b h
