    Answer:

    1 : 2.56

    Step-by-step explanation:

    Since the sign and the banner are similar, their ratio of length to width should be the same. Hence, 32/45 = 20/x, with x being the width of the school banner.

    32/45 = 20/x

    32x = 20*45

    x = 900/32

    x = 28.125 inches

    Now, we can calculate the area of the school banner and the sign:

    Area of school banner:

    28.125 * 20 = 562.5 square inches

    Area of sign:

    32 * 45 = 1440 square inches

    Hence, the ratio of the area of banner to the area of sign is:

    562.5 : 1440

    1 : 2.56

    Hope this helped!
