Determine the amount of square centimeters in the area of the piece of paper using Sophie's measurements.(I got 618.45 sq cm)

Determine the number of square centimeters in the actual area of the piece of paper. (I got 613.44 sq cm.)

Determine the relative error in calculating the area. Express your answer as a decimal to the nearest thousandth. (I don't know how to do this part.)

**drwls**, Saturday, May 30, 2009 at 12:20pmYou computed the measured area, 618.45 cm^2, correctly.

The true actual area, 613.44 cm^2, is also correct.

The relative error is

(measured-actual)/actual = 5.01/613.44 0.008167 = 0.008 (to the nearest thousandth)
