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:

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:

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?
