Calculating Areas of Shapes

The video tutorial explains how to calculate the area of basic shapes such as rectangles, triangles, and squares. It begins with rectangles, using length and breadth to find the area, and then moves on to triangles, introducing the formula of half the base times the height. The tutorial also covers squares, emphasizing the use of side length squared. Additionally, it discusses unit conversion for area calculations and concludes with composite shapes, combining rectangles and triangles to find total area.

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

• Length x Length

• Length x Breadth

• Length + Breadth

• 2 x (Length + Breadth)

How do you calculate the area of a triangle?

• Base + Height

• 1/2 x Base x Height

• Base x Height

• 2 x (Base + Height)
