The following measurements were obtained for the length and width of a series of rectangles. Each measurement was made using a ruler with the smallest scale marking of 0.1 cm. Black rectangle: l = 12.00 cm, w = 10.40 cm Red rectangle: l = 20.20 cm, w = 2.42 cm Green rectangle: l = 3.18 cm, w = 2.55 cm Orange rectangle: l = 13.22 cm, w = 0.68 cm a. Calculate the area (length × width) and perimeter (sum of all four sides) for each rectangle and express your results in square centimeters and centimeters, respectively, and give the correct number of significant figures in the result.
