I have created the PowerPoints below which review step-by-step how to calculate the perimeter and area of basic shapes. While marking the "Area and Perimeter" handouts, I could see that many of you had difficulty using the perimeter formulas of rectangles, trapezoids, and circles and the area formulas for triangles, trapezoids, parallelograms, and circles. Almost all students also had difficulty with the perimeter and area formulas for semi-circles.
To do well on our next section on composite figures as well as on the EQAO test at the end of the year, you will need a firm grasp of how to determine the perimeter and area of basic figures.
You will be expected to review your "Area and Perimeter" handout and make all corrections when you get it back. You may use the PowerPoints listed below to help you make corrections.
