Exploring the Area of Triangles in Grade 6

The video tutorial covers the concept of calculating the area of triangles and rectangles. It explains the formula for the area of a rectangle as length times width, and for a triangle as half the base times the height. The tutorial includes several examples to demonstrate the calculation process, emphasizing the flexibility in the order of multiplication. It also addresses how to handle triangles with unusual orientations or shapes. The video concludes with encouragement to seek help if needed and provides contact information for further assistance.

What is the formula for calculating the area of a rectangle?

• Base * Height / 2

• Base + Height

• Length * Width
