Effects of Changing Dimension

How does changing one dimension affect the area of a figure?

If you double just the base or the height of a rectangle, what do you think will happen to the area?

  1. Choose a base and a height
  2. Double one, either base or height
  3. How did the area change?

Give an example of what happened:

  1. What base/height did you start with?
  2. What area did you start with?
  3. What was the area after you doubled either base or height?
  4. Describe the change in area.

If you double just the base or the height of a triangle, what do you think will happen to the area?

  1. Choose a base and a height
  2. Double one, either base or height
  3. How did the area change?
  • If you change the side length of a square or the radius of a circle, how will the area change?

    Give an example of what happened:

    1. What base/height did you start with?
    2. What area did you start with?
    3. What was the area after you doubled either base or height?
    4. Describe the change in area.

    Does changing just base or height affect area the same as changing a side in a square or radius in a circle?

    Give an example of what happened:

    1. What base/height did you start with?
    2. What area did you start with?
    3. What was the area after you doubled either base or height?
    4. Describe the change in area.
