Finding Area of Shapes: Rectangles, Squares, Triangles, and Circles

This video tutorial by Mr. Jay covers how to find the area of various shapes, including rectangles, squares, triangles, and circles. It begins with an introduction to the concept of area as the surface a shape covers. The video then provides detailed explanations and examples for calculating the area of each shape using specific formulas: length times width for rectangles, side length squared for squares, base times height divided by two for triangles, and pi times radius squared for circles. The tutorial also includes visual aids to help understand the concepts better.

What formula is used to calculate the area of a rectangle?

• Length + Width

• Width - Length

• Length x Width
