Measure the length and width of the floor. |
Would a ruler or tape measure be the right tool for

*Hint*: How big is your shoe? Are there any floor tiles

Measure windows, doorways, and closets. |
*Hint*: Do not worry about
measuring the height of windows and doorways; in a floor plan

walls meet at weird angles that are not 90°? *Hint*:
Can you divide the floor into rectangles? |
