  ```Can rectangles with a different area have the
  same perimeter as this rectangle?
  In this lesson you will learn that
  rectangles can have the same
  perimeter but different area by
  building rectangles and organizing
  information in a chart.
  Let’s Review
  Perimeter tells us the distance that goes around a
  polygon.

  Extension Activities
  Sally asked her father to build a fence around her backyard.
  Her father bought 24 feet of fencing. Use square tiles to
  make the rectangles and then make a chart to find the
  biggest area for Sally’s backyard.
  Extension Activities
  Using square tiles, create as many rectangles as you can with
  a perimeter of 36 units. Circle the rectangle with the biggest
  area. Create a chart to show the different areas for the given
  perimeter.
  Extension Activities
  This rectangle has a perimeter of 18 units. Fill in the
  chart to show the possible areas.

  Quick Quiz
  Here are some rectangles with a perimeter of 18 units.
  Circle the rectangles with an area greater than 10 square
  units.
  Quick Quiz
  Here are some rectangles with a perimeter of 12 units.
  Circle the rectangles with an area greater than 7 square
  units.
