Area and Perimetre
- 1. SS6.2 Extend and apply understanding of perimeter of polygons, area of rectangles, and volume of right rectangular prisms (concretely, pictorially, and symbolically) including: relating area to volume comparing perimeter and area comparing area and volume generalizing strategies and formulae analyzing the effect of orientation solving situational questions. Things to explore: 1. How many rectangles can you make with a perimeter of 16 units? What is the area of each? 2. What happens to the area of a rectangle as you increase the perimeter? Problem: Tinas puppy has a pen that measures 2 m by 3 m. Because her puppy has grown so much, her dad plans to double the length and width of the pen. What will happen to the area of the pen after her dad makes these changes? Another problem: A and B are two flat rectangular fields. The fence around field A is longer than the fence around field B. Does that mean that field A has a greater area than field B? Explain and use a model or sketch to support your solution.
