Final answer:
You can use measurements to fit shapes together and determine the required size of a page.
Step-by-step explanation:
When putting shapes together, such as L's into a square, you can use measurements to ensure precision.
For example, if you have L-shaped pieces that measure 6.5 units, 4.5 units, and 11 units, you can add these measurements together to determine if they can fit the page. In this case, the sum of the measurements is 22 units, so you would need a page that is at least 22 units wide to accommodate the square.
