1. Measure the rectangle dimensions

Stretch the divider, and measure the length of the rectangle in question. Use several strokes if the length is bigger than the stretch of the divider. Transfer the divider to the ruler, and read the measurement. Make sure not to tamper with the stretch of the divider during the transfer to avoid an inaccurate measurement. The value you get is the length of the rectangle in question. Use the same procedure to get the value of the width.

2. Record the measurement

Using a pen and a paper, record the measurements of the length and the width. You can verify the measurements by repeating the measurement procedure.

3. Calculate the area

Multiply the value of the length by the value of the width to get the area of the rectangle. For instance, if the length of the rectangle is 20 centimeters and the width is 12 centimeters, the area of the rectangle is 240 square centimeters.
