Can other rectangles have the same area as this one?

Can other rectangles have the same area as this one?. In this lesson you will learn that rectangles can have the same area but different perimeter by building rectangles and organizing the information into a chart. Perimeter tells us the distance that goes around the polygon. Perimeter.

  1. Can other rectangles have the same area as this one?

  2. In this lesson you will learn that rectangles can have the same area but different perimeter by building rectangles and organizing the information into a chart.

  3. Perimeter tells us the distance that goes around the polygon. Perimeter

  4. Width Length

  5. Mixing up area and perimeter. Area Perimeter

  6. Area = 9 square units Area = 9 square units

  7. Perimeter = 20 units Perimeter = 12 units

  8. Rectangle #3 Rectangle #2 Rectangle #1 Rectangle Perimeter Length Width Area 16 units #1 2 units 6 units 12 square units #2 4 units 3 units 12 square units 14 units 26 units 12 units 1 unit 12 square units #3

  9. Rectangle #1 Rectangle #3 Rectangle #2

  10. Rectangle Perimeter Length Width Area #1 20 units 8 units 2 units 16 square units #2 16 units 4 units 16 square units 4 units #3 34 units 1 units 16 units 16 square units

  11. In this lesson, you have learned that rectangles can have the same area but different perimeter by building rectangles and organizing the information into a chart.

  12. Can rectangles with a different perimeter have the same area as this rectangle?

  13. Rectangle #2 Rectangle #1 Rectangle Perimeter Length Width Area #1 8 units 2 units 2 units 4 square units #2 10 units 4 units 1 units 4 square units

  14. Sally asked her father to build a fence around her backyard. Sally wanted the backyard to be 36 square feet. In order to have the biggest backyard, Sally’s father would need to buy more fencing. Create a chart to show how many polygons Sally’s backyard could be with 36 square feet. Then circle the rectangle that would be the biggest (which one has the biggest perimeter)

  15. This rectangle has an area of 8 square units. Fill in the chart to show the possible perimeters.

  16. Fill in this chart. You can use square tiles to help you visualize the rectangles.

  17. Here are some rectangles with an area of 24 square units. Circle the rectangles with a perimeter greater than 24 units.

  18. Which rectangle has a larger perimeter? How much larger is that perimeter? Rectangle #1 Rectangle #2
