Use the PHET Active Simulations Site to answer the following questions.



Question 1: can you build a rectangle with an area of 6 units squared and a perimeter of 10 units?



Question 2: can you build a rectangle with an area of 6 units squared  that has a perimeter other than 10? (i think you can)


question 3: can you build a non-rectangular shape with an area of 6 units squared?


question 4: can you build two different rectangles, both with an area of 24 units squared?


question 5: how many different rectangles can you make that each have an area of 24 units squared? what are the perimeters of each one?


Question 6: how can you use length, width, area, factors and products to make sure you've found all the rectangles?
