Step 2: Measure

Now that you know your rectangles, you are ready to measure each rectangle’s length and width in inches. Below are sample measurements for the floorplan from Step 1.

When you measure a rectangle, be sure to write down its measurements. We recorded our measurements as shown next to the floorplan. There is no right or wrong way to record these measurements, but this format will make Step 3 a little easier.
