How to Use

Use the red points to adjust the size and location of the rectangle.

Buttons

• Show/Hide Base and Height- will reveal those measurements (rounded to the thousandths).
• Show/Hide Area- will reveal the area, rounded to the hundredths.

Click and drag the measurements around the workspace as you wish.

Before using any of the buttons, explore the following:

• Knowing that the background is a cm. grid, how can you estimate the area of the rectangle?
• What is the relationship between the base, height, and area of the rectangle?
• Write down a real-world scenario that would require you to know the area of a rectangle.
