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?

- Choose a base and a height
- Double
__one__, either base*or*height - How did the area change?

## Rectangle

Give an example of what happened:

- What base/height did you start with?
- What area did you start with?
- What was the area after you doubled either base or height?
- 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?

- Choose a base and a height
- Double
__one__, either base*or*height - How did the area change?

## Triangle

Give an example of what happened:

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

If you change the side length of a square or the radius of a circle, how will the area change?

## These side lengths will not change in the activity.

## Square

Give an example of what happened:

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

## Comparing two different dimensions verses two of the same.

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