7576 ask about the A series of paper. Many countries use A4 paper, which is somewhat different from the 8.5 by 11 inch paper standard in the US.31 A4 is part of a series of paper sizes specified in ISO 216, an international standard. Two sheets of A4 paper, if laid side by side (not end to end), are the same size as one sheet of A3 paper. Likewise, two sheets of A3 are the same as one sheet of A2, and so on. See Figure 1.73. Each sheet in the series has the same proportions, length to width, and the largest sheet, A0, has an area of exactly 1 m2.Let f(n) be the area in cm2 of the size n sheet in the A-series, so that f(1) is the area of A1 paper, f(2) of A2 paper, and so on. Since 1 m equals 100 cm, we know that f(0) = (100 cm) 2 = 10,000 cm2. Complete the table of values of f.
