| Measure the length and width of the floor. | Would a ruler or tape measure be the right tool for the job? What other methods can you use to measure the floor? Hint: How big is your shoe? Are there any floor tiles in your classroom? What is the size of one floor tile? |
| Measure windows, doorways, and closets. | Hint: Do not worry about measuring the height of windows and doorways; in a floor plan everything is flat. |
| Calculate the area and perimeter of the floor. | Remember that A=L x W. Does the floor have an irregular shape? Do the walls meet at weird angles that are not 90°? Hint: Can you divide the floor into rectangles? |
