Example: a piece of paper

Example: “I think it can fit about 8 inches across and 10 inches down, so square inches work well. It can be measured in square centimeters, too, but would just take a lot more squares. Square feet and square meters would be too large.”

## Problem 1

For each object, decide if you would use square centimeters, square inches, square feet, or square meters to measure its area. Explain your reasoning.

1. a baseball field

2. a table top

3. a cell phone screen
