1 Copyright Tim Morris/St Stephen's School Area of a Rectangle This is one in a series of Powerpoint slideshows to illustrate how to calculate the area of various 2-D shapes. Start with the Rectangle, then move onto the Parallelogram. After that select any of Triangle, Trapezium and Circle. Please feel free to copy and modify any of these slide shows, but make sure you acknowledge the author when doing so.

2 Copyright Tim Morris/St Stephen's School RECTANGLE W=width What is the area of this rectangle?

3 Copyright Tim Morris/St Stephen's School RECTANGLE W=width H=height What is the area of this rectangle? DIVIDE IT UP INTO SQUARES!

4 Copyright Tim Morris/St Stephen's School RECTANGLE W=width H=height What is the area of this rectangle? CHOOSE STANDARD SIZE SQUARE!

5 Copyright Tim Morris/St Stephen's School RECTANGLE W=width H=height What is the area of this rectangle? CHOOSE STANDARD SIZE SQUARE!

6 Copyright Tim Morris/St Stephen's School RECTANGLE W=width H=height What is the area of this rectangle? COUNT THE SQUARES…

7 Copyright Tim Morris/St Stephen's School RECTANGLE W=width H=height What is the area of this rectangle? AREA = 63 STANDARD SQUARES

8 Copyright Tim Morris/St Stephen's School RECTANGLE W=width H=height What is the area of this rectangle? BUT THERE IS ANOTHER WAY!

9 Copyright Tim Morris/St Stephen's School RECTANGLE W=width H=height What is the area of this rectangle? COUNT THE ROWS…

10 Copyright Tim Morris/St Stephen's School RECTANGLE W=width H=height What is the area of this rectangle? COUNT THE COLUMNS…

11 Copyright Tim Morris/St Stephen's School RECTANGLE W=width H=height What is the area of this rectangle? THERE ARE 7 ROWS OF 9 COLUMNS

12 Copyright Tim Morris/St Stephen's School RECTANGLE W=width H=height What is the area of this rectangle? THERE ARE 7 x 9 = 63 STANDARD SQUARES

13 Copyright Tim Morris/St Stephen's School RECTANGLE W=width H=height What is the area of this rectangle? Area rectangle = Rows x Columns = Width x Height

14 Copyright Tim Morris/St Stephen's School RECTANGLE W=width H=height Area rectangle = Width x Height (perpendicular height H)
