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.

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)
This rectangle has an area of 8 square units. Fill in the chart to show the possible perimeters.
Fill in this chart. You can use square tiles to help you visualize the rectangles.
Here are some rectangles with an area of 24 square units. Circle the rectangles with a perimeter greater than 24 units.
Which rectangle has a larger perimeter? How much larger is that perimeter? Rectangle #1 Rectangle #2
