    The area of the given rectangular index card = 9677.4 mm²

    Explanation:

    Area is defined as the space occupied by a two dimensional shape or object. The SI unit of area is square metre (m²).

    The area of a rectangle (A) = length (l) * width (w)

    Given dimensions of the rectangle: Length (l) = 5.0 inch, Width (w) = 3.0 inch

    Since, 1 inch = 25.4 millimetres (mm)

    Therefore, l = 5 * 25.4 = 127 mm, and w = 3 * 25.4 = 76.2 mm

    Therefore, the area of the given rectangular index card = A = l * w = 127 mm * 76.2 mm = 9677.4 mm²
