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.
Perimeter tells us the distance that goes around a polygon. Perimeter
Width Length
Mixing up area and perimeter. Area Perimeter
Perimeter = 10 units Perimeter = 10 units
Area = 6 square units Area = 4 square units

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.
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.
This rectangle has a perimeter of 18 units. Fill in the chart to show the possible areas.
Fill in this chart. You can use square tiles to help you visualize the rectangles.
Here are some rectangles with a perimeter of 18 units. Circle the rectangles with an area greater than 10 square units.
Here are some rectangles with a perimeter of 12 units. Circle the rectangles with an area greater than 7 square units.
